Here's my current setup; I dropped a SSA-E in it, put on an Ergo, put on a PWS FSC30, mounted a Monarch 2-7 scope, and threw a bi-pod and gg&g vertical foregrip on it. Also, I was able to shoot it out to a 100 yards out at the cabin this week with some hand loads and was pretty pleased with the results. Pics if you're interested. http://dl.dropbox.com/u/11353464/Forums/901/Photo%20Apr%2002%2C%204%2053%2058%20PM.jpg http://dl.dropbox.com/u/11353464/Forums/901/Photo%20Apr%2002%2C%204%2048%2022%20PM.jpg http://dl.dropbox.com/u/11353464/Forums/901/Photo%20Apr%2005%2C%209%2004%2018%20PM.jpg http://dl.dropbox.com/u/11353464/Forums/901/Photo%20Apr%2005%2C%209%2006%2057%20PM.jpg Did they say what they did to fix it? Hi, not really I even called to ask and they told me they couldn't ask the gun smith who did the work. I assume mine was an issue with the carrier striking the forward assist as it traveled rearward. I used to be able to feel it get caught up on it when I pulled it back and forth by hand and I no longer feel it catching. I know for sure they put a new gas key on it, so maybe that was it or a combination of both. Anyway it works great now and I'm finally a happy customer :) Okay...Mine's all fixed...Tubbs buffer spring... not one single failure to feed, failure to lock back or any other issue from 6 different magazines and about 150 rounds...and it didn't cost me 3 months of wondering when I'd get it back...very pleased...I LOVE the way this thing shoots...especially now that I can actually do so without concern or consternation. |

Mine had a slight burr on it that I polished out...there are pics of that somewhere in this thread I think. yep..saw your pics. I think it is what we can expect. |

Removal of the mag sends bolt forward. 3.Failure to feed / failure to strip next round from magazine 4.Failure to feed / Bolt hits the next round in the middle of the cartridge Colt customer service was great. Sent me the Fedex lable to send it in to warranty repair on their dime. I really hope it doesn't take months. I hate sending guns through Fedex in this current climate. Always scares me that something will go wrong. Anyone else also having these issues? Yes. Interestingly the problem went away, almost, with the use of a DPMS magazine. Radway Green 89 failed to run the bolt back far enough to lock open even with the DPMS mag. It also grouped around 2.5" lower than the Federal XM80 used that day. http://i50.tinypic.com/j7f38o.jpg If you can't tell from the picture, the cartridge "hump" on the follower of the DPMS mag extends further to the rear than on the Magpul follower. When hand cycling with the Magpul mag, as soon as the bolt passes the cartridge "hump" the bolt catch rises. As the bolt continues rearward the rear of the lug on the bottom of the bolt contacts the bolt catch. This does not occur with the DPMS mag. http://i50.tinypic.com/33k53dk.jpg This is the bolt catch profile on my rifle. Wondering if others are the same. The arrow indicates the most severe contact point of the bolt lug. http://i48.tinypic.com/2nhkltl.jpg Anyone with a more recent version of the 901 want to post some pics to compare? Mine is SN >150 By the way, the DPMS mags, of two, one barely fits in the magwell the other might go in if forced. Mine is a real early 600 SN and based on your picture the profile of my bolt catch looks a little different. . . https://dl.dropboxusercontent.com/u/11353464/Forums/901/Photo%20May%2019%2C%2014%2017%2013.jpg https://dl.dropboxusercontent.com/u/11353464/Forums/901/Photo%20May%2019%2C%2014%2022%2049.jpg |

First post, just checking in. Just picked up my 901 a few days ago MCC0015XX, 2013 config. Why do we not show the full serial?
Thanks for all the info and inspiration. Just have to find time now to give it some attention; sure is purdy. |
|
|
Did it come w/ the magazine well upper adapter? You don't show the full serial on the off chance someone will mill an identical lower, forge your serial number, murder someone w/ it & leave it @ the scene of the crime. Or, just b/c everyone else does.

I was told the following by a "Customer Service Supervisor" at Colt yesterday afternoon:
A. They have not yet began shipping adapter blocks with 901's, despite what the website says about the April date. B. They do not even have a projected date yet for adapter block availabilty for current 901 owners. C. They are very much aware of the frustration and in some cases anger on the part of 901 owners who fully expected to be able to obtain adapter blocks a while ago, however the current market climate, and continued high demand, blah, blah, blah, etc., etc., etc. The next time I feel like making a 35 minute phone call that will leave me more frustrated than when I started, I'll just start drunk dialing my exgirlfriends. |

Or, just b/c everyone else does. Did not come with the adapter. One magazine, a set of quick detach sling swivels and a shot lock is all I was blessed with. The current 2013 config is a bit of a let down, but I've got a 901 now so I'm not going to complain much. |

I apologize if I missed this in the last 67 pages. Is the charging handle on the 901 proprietary? I read on another forum that it was; does this check with the 901 experts here?

Thanks for the update (or lack there of) on the adapter block. My local Academy just got in a Promag LR-308 for $25 which is supposed to be DPMS/SR-25 compatable, but upon getting home found it would barely fit in the magwell and would not seat on a closed bolt, so i guess we have to wait on Magpul or the new Lancer 25rd mags.

DSG Arms received a small shipment of LE901-16S. I was lucky enough to snag one of them, for an excellent price. So if you've been in the market for a long time like me, JUMP.

I throw a muzzle brake on it when used in that capacity. Had pulled the brake off and thought I'd give the A2 a whirl. I think it "looks" better but have not fired it with the A2 yet. |

From Colts website: Note: All LE901-16S models manufactured after April 1st, 2013 will be shipping with the magazine well adapter block needed to mount MilSpec 5.56 Colt upper receivers to the LE901-16S lower receiver.
I just ordered my 901 so hopefully theyll start shipping with them but has anyone received a rifle made after 4-1-13 and receive the mag well adapter block yet? http://www.coltsmfg.com/Catalog/ColtRifles/ColtLE90116S.aspx |

Which begs the question, what about the guys who already own one (and were nice enough to post on here with their experiences)?
Do they get a voucher? |

My dealer I ordered from still has them at $1899.95 and i think it was that price way before May.. |

Colt's MSRP pdf showed the 901 at ~2400 if I recall correctly.

I checked one of the distros I deal with regularly and dealer pricing for the 901 has indeed increased. Around $200 more than when I paid dealer for mine.

Well I have one and I also have some serious problems that I need help with and cannot get the answers. I would post all the problems if someone(s) want to help but one solution that I will not take is to take the suppressor off. The gun is an LE901-16s (Colt) .308. It has a Thunderbeast 30-p suppressor, a 5-20x50 Trijicon accupoint w/ green dot and mil dot reticle, Trijicon quick release scope mount, Atlas bipod with quick release mount, Syrac Ordnance low profile adjustable gas block and a Geissele ssa-e trigger. At times the spent shell will stay chambered, once it's removed the side of the rim is pulled off, which now has caused other problems. I need help/suggestions please

It is not included in the purchase of the gun . Never was meant to be. That is why no one has one. However you can purchase one later this summer for approx $300.00 which will include the buffer tube and spring. I have been told so many stories by Colt over this adapter. This is the latest one. They can choke on it.. I don't need or want it. First story was that it was coming with the purchase of an upper receiver, then they changed and kept changing their story. If you don't believe me, call them. I have and I've had my gun since Sept of 2012. My serial # is 522 they have made only 4500 guns since they started ( this is per Colt) and I am no longer waiting on a nonexistent / mythical adapter. And yes, I'm pissed off. |

Eventually I would like to suppress it, but that will have to wait. Also I intend to try the KAC 45 deg sights on it, but I don't know how well that will work out. Don't you do it, don't do it (suppress). You will have more problems than you will care to deal with. Rims pull off of shell that are stuck in chamber, when you get case out it will be blackened (overgassing), your Geissele trigger (ssa-e) will start doubling due to all the gas trash that is in your lower receiver. Here is how you fire a suppressed LE 901: after firing you will notice that it won't fire again, drop the mag, pull the bolt back if you can (this can be a problem), when you get the bolt back make sure it locks and doesn't slip out of your fingers and goes back into battery, once locked back assemble your cleaning rod and drop it down the muzzle and the spent casing should fall out, look at the rim and you will see that it has been peeled of on the side where the extractor grabbed it, clean your chamber and try again. Keep the cleaning rod out, you will need it as long as suppressor is on barrel. Ammunition does not matter, I have tried them all. Changing mags does not matter. Taking off the stock gas port ( Troy flip-up sight) and installing a Syrac low profile adjustable gas block will not help. I know this because I shoot my gun. I had no problem till I put a suppressor on it. Colt will not help me because I have modified the gun (suppressor). They sent me a shipping label to return the gun but they said they will not fire it suppressed. They told me it was my problem. Ok, I changed my mind. Please put a suppressor on it so that when you have problems I won't be the only one and maybe Colt will listen to two people instead of one. yeah, right. Good luck on the suppressor if you decide to go that route. Did I mention that your (my) Geissele ssa-e trigger will start doubling and you will get kicked off the range? However all is not lost, load one round at a time in your magazine (to prevent doubling), eject the stuck cases with your cleaning rod (the opposite of the black powder operation, you know, you're knocking the shell out not seating a patch and ball, clean chamber and get ready to look cool pushing your ramrod down your suppressed modern sporting rifle to eject your stuck case. Hey the other folks think you're just cleaning it after every round. No I'm not taking the suppressor off. There has to be a fix somewhere, somehow before I demilitarize this beast. |

Piston, perhaps? Figures the mag well is unobtainable, and then when it will ship, it'll be price-prohibitive. That's ok. Once more than 3 ship, some one will be making them for $50 - it just won't say Colt.

With all the hype, and all the advertising, almost a year has gone by since people have had 901's. Go ahead and blame it on the mass hysteria in the gun business over the last six months, it is a single part. One single part. I am a life long Colt fan, I buy many Colt products, and quite frankly I will continue to do so. With that said, this situation with the adaptor is a huge disappointment. |
|
|
agreed jagd... I have two 901s
will continue to buy from Colt adapter situation is bullshit |
|
|
Purchased LE901 in Oct, 2012.
Will not continue to purchase new Colt products. Adapter situation is, indeed, bullshit. |
|

Just thought Id provide a little insight. Its is stated on the Colt website that beginning April 2013 (date of manufacture) they would begin shipping with the adapter. I was told today by a source at Colt that they actually started shipping only about 2 weeks ago. They are in the process of finalizing retail packaging and they will have the adapters on the coltsmfg.com site around 2 weeks or so with an estimated price of $300.
I have some open questions for anyone. I had to get some specific details on my particular rifle and spoke to Colt Archives. They had an issue finding by serial number but finally tracked it down. Apparently almost all semi-auto LE901-16s were sold by Colt Manufacturing, however mine was sold to the distributor directly from Colt Defense. Does this change anything at all? The standard config? Mine is marked Colt Defense on the right side, is that the same as all others? Does the .308 bolt have 2 locking points? I though it was catching on the mag lips, but releasing the mag or removing it altogether still enables 2 catches; both release using the bolt release. There is maybe 1/4 inch difference between them. Is this for the difference in .308 / 5.56 uppers? I'm dumbfounded. Is the safety selector the same as a standard "AR" type selector? Anyone recommend a specific ambi-selector? The main reason I bought this rifle to use in conjunction with a AAC SDN-6 that I have. I haven't tested it yet... but now people are saying it doesn't cycle for shit with a suppressor? WTF COLT? http://imageshack.us/a/img802/7364/photo13ab.jpg |

So if I understand this correctly, I'm hearing that those of us with the "2013 Config" are getting royally screwed. Those before us received the extra mag, cleaning equip and a sling. Those after us are going to get the adapter. I'm glad I've got a 901, but I'm feeling a little ripped off right now. Thanks for all the pics though peeps.

|

I agree with you. I bought this rifle with the assumption that the adapter was included (as per the website) as it was bought just a couple days ago. Thus is life I suppose. Colt knows they will catch a lot of flack for the issue.

Overgassing,
I'm interested in your suppressor issues - I'm planning on getting a 901 and want to suppress it, too. Having been to Specialized Armament's AR-15 Armorer courses (taught by Ken "The Colt Whisperer" Elmore), suppressing an AR platform weapon requires a barrel with a properly sized gas port and proper buffer. I see that you tried an adjustable gas block with no success. If I have to rebarrel a 901 to get it to run properly with a can, I may get a SCAR 17 instead. |

Talked to Chris at Noveske today. Noveske matches the port in their barrels to their own switchblock. He did not think one of their blocks would work for me unless i got a Noveske barrel to match it with. He suggested I try a much heavier buffer to slow down my bolt. After spending much of his time with me, his thoughts were that I should have gone with the heavier buffer before trying to fix a gas issue.The port matching from barrel to gas block is very critical to the gas operation which is the first concern I spoke about with Jason from Syrac. Jason even told me the gas pressure of a .223 was more than a .308....... I should have known right then that the Syrac adj. gas block was a bad deal, but desperate people seek desperate measures. Chris @ Noveske suggested I look at Rainer Arms to get a buffer. I'm also looking into Spikes Tactical buffers. I'm willing to try most anything except for the last two suggestions from other people which is to get rid of the LE and get something else or take the suppressor off. Eventually I will get it figured out or I will post a link to a vid of the first demilled LE901. But right now I need to find a heavier buffer. I'll keep posting to let y'all know cause I think I'm the only one in the world right now with these problems. I am going to the range tomorrow to try to qualify at 1000 yards. I got my 180 gr bullets and my trusty ramrod extractor at the ready. Just hope they don't call for a rapid fire, but I am getting faster at removing my stuck casings

This could be a solution to F2F but how does that help rounds that are stuck in the chamber? Anyways... I like the way you think brother. Keep us informed if you find a solution before I do. |

Hello, David, MAN, this could be a section right out of my Police/Military Advanced M16 Armorer Classes. I warn the COPS constantly about situations like this. I cannot really help you because I cannot "FIX" this situation. Here's why. A suppressed weapon has got to be built/engineered around its sound suppressor (Most CRITICAL Element). This usually requires a special barrel assy with its own gas port (SMALL). NO ONE builds this for the 901's. YET. The "gas issue" CANNOT be solved with a heavier buffer. In my opinion (based on 25 yrs experience) - the adj gas blocks are expensive JUNK. A SUPPRESSED COLT 7.62 weapon is gonna require some extensive engineering/testing and custom parts. None of which exists at this point. Unfortunately you are learning that standard weapons cannot be easily suppressed. Suppressed weapons are sophisticated animals. Right now you are trying to combine a bunch of parts that were never developed to work together. No one says this on the forums do they? These "open fora" are tightly controlled and big business. My only advise would be: Put that Colt weapon back to its factory configuration. I bet COLT will help you turn it back to a stock 901 if needed. Sorry that I cannot work any magic for you in this situation. Good Luck, Ken Ken Elmore Owner, Operations Supervisor Specialized Armament (1990 - Present) Instructor, Police & Military Weapons (1988 - Present) Sergeant, US Army (1986 - 1990) Quality never quits |

Syrac is exactly who I was talking about. A least Noveske didn't try to sell me something that won't work. Honesty means a lot to me and to everyone I hope, but some people just want your money. Thanks for mentioning Ken. Sometimes the truth really hurts, but saves the pocketbook. I hope this helps anyone looking to suppress an LE 901. Instead of wasting your money, send it to me.

FWIW..... You already know your 901 is overgassed while suppressed. It runs fine (IIRC) while unsuppressed, so your barrels port size is correct for unsuppressed usage. The next step is either slowing the cycle down through a heavier buffer, or reducing the gas flow by using an adjustable gas block. If your current setup is ripping rims off, then you might not find a buffer heavy enough to slow down the unlocking phase far enough to correct that.
As far as what people are saying about adjustable gas blocks: Your barrel's gas orifice has already determined what the maximum pressure allowed to your system is, and it appears to be the correct one for unsuppressed usage. The next step is having an adjustable block that can reduce the pass-through orifice size to an acceptable level. If you can find a heavier buffer that will help slow things down while still working in semi unsuppressed mode, that would net you a little wiggle room. Either way, this problem (as described) definitely seems to call for an adjustable block. It sounds to me (if I'm reading correctly) like your Syrac block simply isn't reducing the gas flow enough. If Noveske made/makes a switchblock that would fit your barrel, is it possible to get one with only a tiny pilot hole drilled in the correct locatiion? If so, then you could very gradually enlarge the port in the switchblock until your rifle achieved reliable function..... If possible, I think that could solve your problem. |

Yes Variable656 you are reading correct. The gun is just fine unsuppressed. I called Colt to find out what size the barrel port is so that I would know what size of gas block to get to match the barrel port. This is the reply I got from Colt: Hello Sir,
After speaking with the Product Service Manager, the information your seeking is not public information. We apologize that we couldn’t be of more assistance. Sincerely, Jaz McDaniel Customer Solutions Specialist Colt's Manufacturing Company, LLC. P.O. Box 1868 Hartford, CT 06144 (800) 962-2658 x 1450 So, this lead to a conversation with Jason at Syrac which led me to my purchase of the adj gas block. When the gas block arrived I took my front sight / gas block off and measured the barrel port which is approx half the size of the port in the Syrac adj gas block. From what I can find out all the gas blocks, either adj or not, all have a .125 hole. All of the manufacturers that I talked to have the same .125 hole in the gas block, only Noveske makes different sizes to match THIER barrels. Here is their reply: David, You will have to order one that is a clamp on for your barrel length and gas system. Make sure that you know the size of your gas block seat. We will not make a custom one. You need to keep an eye on the website or check with one of our distributors. I still suggest that you try a heavier buffer. Regards, Chris Noveske Rifleworks LLC Phone: 541-479-6117 Now I just need to get someone to make me a custom one, but even Stevie Wonder can see that's not gonna happen. And so it goes.....take off suppressor,take off non working Syrac adj gas block, clean my Geissele trigger, (so it will quit doubling from all the gas trash), put stock front sight / gas block back on and enjoy my non suppressed LE. .............. By the way the gas port hole in the LE is between .062-.078 inch, but that is not public knowledge per Colt. But I do thank everyone for their suggestions |

I haven't seen the inside of a switchblock, so I can't know whether this would work or not, but what if you were to use a switchblock and simply drill the "off" setting in tiny increments until it becomes your new "suppressed" setting?
Shawn and others: I know this is a 901 thread, but since it's about getting one to run with a can (pretty darn desireable these days), it seems pertinent. Anyone have pics of a switchblock's guts? It might even be that the "suppressed" settings port could be welded up and redrilled for a 901. All of this is predicated on the 901 having an acceptable barrel journal diameter to fit a switchblock to begin with. What's the diameter on the 901? |

It's .750 ....but that's a great idea to use on my Syrac adj block. Since its a clamp on I should be able to get the correct angle to drill it after welding... Great idea, Thanx |
