[ARCHIVED THREAD] - Project 723 (Page 2 of 2)
Yes, the 653, 733, and 723 are most popular in Israel, and are put to good use there. Also keep in mind that quite a few of thier carbines are "mixmasters", along the line of US Air Force stuff. |
It is possible for a 723 to have ramps extending into the upper receiver. Mine does not. If you did find one, it would be an earlier version, not the modern M4 feed ramps. Info on various Colt Carbine feed ramps here: www.ar15.com/forums/topic.html?b=3&f=118&t=283545 |
LOL...I am glad you asked!!!! An A1+ is part of my "Advanced Retro" program that I designed for me. I personally find the "modern" AR - 15 A2 series a bit of overkill. The front heavy barrels are nearly useless, the rear sight is much more complex than necessary and the reasr stock on the rifle version is wayyyy too long. I also prefer the Triangular Hanguard to the round...however the round is superior at least as far as materials goes. However there are SOME good things about the A2. There really isn't a need for a beefier lower but the added weight is nil so it's an OK thing. The brass deflector on the upper is a good idea....especially if you're a lefty. The newer M4 stock is more condusive to a good cheek well but that is for another discussion and the birdcage flash supressor with the lower ports blocked is also a good idea. What I have done is combined the "best of both worlds" and built an AR that sticks to the LIGHT RIFLE concept but has just the right amount of improvements to make it more of a "universal" rifle. Here's my A1+ rifle.  Mostly Colt with a Fulton ( DPMS...dammit ) C7 upper and a Hogue grip, Turner Saddlery Synthetic sling, AR15A2 lower and a pencil barrel ( 1/12 ) on the upper. Note the Delta ring instead of a standard Slip ring. This still has an A1 flash hider at the moment but I'll eventually change that. |
Hey DM - Cool rifle - To keep the them going you need a Colt "CS" stock as well!  The length of the original A1 stocks but the strength and storage of the A2 stocks.Question for you, I read somewhere (maybe from you?) that the DPMS\Fulton Armory A1 uppers have a slightly narrower CH slot and because of that, you need to use a DPMS\Fulton Armory CH with that upper? Has that been your experience? |
Here's mine. All bushmaster save for the small accessories and telestock I really prefer the newer 6 pos waffle telestocks ove the old 4 pos. No rattle and it's more comfy on length and cheekweld. I also insist on the M4 handguards. The pencil barrel gets hot quick and the CAR handguards with the vent holes straight into the barrel let out too much heat on the hand. I'm very happy. |
|
CMMG states they're hoping for MID AUGUST m4 feedramps, f marked FSB 14.5, 14.7, 16 all in carbine and then middies (minus the 16" i believe) they said they will probably start taking orders when shipped for chroming process prices will be around the same as their other bbls i'll be on that list for a 14.7"!.....errr...i hope! |
|
CMMG Lightweight barrel updates First F-marked, then standards--all 0.625. A little bumed by the M4 ramps, but that's not a deal breaker. I had heard a rumor about the A1 uppers with M4 ramps in the future. I'm aware that M4 barrel extensions are compatible with all uppers. |
damn I wish I could find one fo those... Onlyoption is noveske themselveswho wanna sell for like 500 with a stock, grip, and parts kit 
|
You can also find a Colt upper of this style with M4 ramps. |
Are you talking about an A1\C7 type upper with factory M4 ramps? If so, I've been looking for one for a while now and haven't had any luck so if you know of any sources? I also didn't have any luck finding a factory Colt 14.5 A1 profile barrel with 1/7 twist either. 
|
Info on A1 uppers with M4 feed ramps from CMMG. If Colt made a run of 14.5" A1 barrels, they could name their price. |
Thanks for the info. Only 2 problems with that... 1. I don't want to wait that long  and 2. CMMG has all of their receiver coated with a Teflon finish. I would prefer the normal Mil-Spec anodizing only.
Very true. I think if BM would make them with a 1/7 twist then they would sell a bunch too. I think the BM's would really sell because they don't use M4 feedramps and with as many people wanting to install these in A1 and A2 uppers which are much easier to find (and much cheaper to buy) without ramps, it would be a good combo. BM would also be able to sell them closer to $200 so price wise they would be pretty attractive too. I think CMMG is going to do very well with their LW line if for no other reason then they will be the only game in town with that many options. |
 Just wanted to post a photo of the inspiration for this build again. The barrel should be available shortly. Here's my shopping list for the upper: CMMG 14.7" Lightweight barrel, with peel washer and A2 FH permanently installed BM Forward assist kit BM A1 rear sight components XS Sights same plane rear aperture, CMT/Stag MP tested bolt and bolt carrier Standard charging handle CAR handguards Any comments on these choices? What are your favorite receiver blocks and wrenches to use? |
I would stick with the 16'' barrel, every thing else looks good . |
The 16" barrel is a deal breaker--this is Project 723, not Project Early 6520. That would be much easier, however. I want to get as close to a 723S (semi) as possible without registering my Noveske lower. That leaves me with a 14.5" with an extended A2, or a 14.7" with a standard A2--both permanently attached. 0.2" is swallowed up over several inches on a barrel, but it is quite obvious when you add 0.2" to a 1.3" FH, in my opinion. |
you guys have convinced me. i'm going to switch to the 723 format. this is my light weight build that has been great, but i have always felt it needed more. i have an C7 upper and A2 grip lying around, and am going to order the Stag CAR stock and a set of CAR HGs. the barrel is a colt 1/7"LW cut to 14.7 w/perm A2. this the before, and i should have afters in a couple of weeks.
|
Looks good. If you've got the money, why don't you use that upper for a GUU-5/P & start fresh for your 723? Can never have enough lightweight CAR's. GUU-5/P  Here's what my 723 currently looks like. I'm working on the GUU. 
|
Ordered mine here: Rainier Arms In-stock & quick shipping. |
|
mine's a Colt 1/7 twist that Lauer did the cut/pin job on. Lauer did a nice clean job, but were quite abit more $ than ADCO or AR15barrel.com, and took 2 months. Bushies are only 1/9 twist - that could be why everyone is waiting for CMMG. i got my stock from STAG last week , and put it on this weekend. i'll get some pics up soon. |
|
Who makes the C7/A1 upper for the 723 with the extended feedramps? Are there any off the shelf versions? I could live without, but CMMG's barrels are sure to have them, but their A1 uppers don't. Also, what's the weight difference between the M4 profile barrel and the "pencil" barrel? And how much weight savings are we looking at exactly between a 723 and an M4? Thanks, ~Augee |
That is modern, like post 1997. |
That's probably a good thing then because then maybe the feedramps will actually match up? I found a Colt C7 upper like that one with the M4 feedramps. I was told it came from a "commando" upper? Anyway, mine was the older Colt gray and the feedramps did not match up with a newer Colt M4 barrel. Ekie or some other Colt historian could probably give you more accurate details about this then I but apparently the original Colt M4 ramp profile does not match the newer profile that Colt and everybody else uses now. |
Yes, there was a different ramp used on some carbines and commandos in the 1987-1992 time frame. Details in the tacked carbine thread. |
|
I am so stoked to get an A1 upper with M4 feed ramps. There is a "4" over the gas tube hole. I know that it doesn't matter, but that will create a seamless fit with the CMMG barrel when available. The receiver is en route to me, so I don't have a really good idea on the finish. Aside from sending it out to US Anodizing to have it balsted and anodized black, what spray on finish would give me the best match to my Noveske lower? |
That upper appears to be modern black. Am not familiar with Noveske lowers, so have no idea what finish is used or what color they are. |
Noveske lowers are/were made by CMT...that may give you some idea about what to expect for the color. |
What finish did these stocks have? The rubber coating like the early ones, or a textured finish? Also, did any of these weapons ever have A2 rear sights? |
Early ones have the vynil stock like on a SP1 carbine. They did not come with A2 sights. |
