Official SAM-R and SDM-R photo and discussion thread.....yep we are doing this again. (Page 8 of 29)

The real KAC front sight gas blocks are seen from time to time for sale. One sold this week on the EE for $550, I hope someone on here got it. Granted it was only up for like 4 min!
and my first page ownage, I guess I will have to post a pic of my still in progress without the barrel parts when I get home.

I only have mine because I took it off a KAC rifle back in the day when I was stupid. Who says stupid doesn't pay off. |

Actually, I think they could of got a lot more if they wanted to. I wouldn't be surprised if one went for $700. |

Has me rethinking the whole SAM-R rifle I'd like to build or at the very least some close enough FSGB. |

I could have but the screw hole does not line up in the middle of the gas tube hole. In the blue print it does but on the gas block I used the screw hole is off set in a way that it would be at the very tip of where the gas hole needed to be. If I had a drill press I may have been able to go that route but all I have is a cordless and that would have been difficult to accomplish. |

Jon, that looks promising, I may go ahead and get 'em. Ill keep you updated on its feasibility. Just make sure to get either the G&P or VFC branded ones should you decide to snag a few. |

Ok, so I got the Colt front sight and have some pictures comparing it to the KAC. It isn't exact and doesn't flip up by spring action, but it's close. Spent about 30 minutes turning it into a functioning gas block. The material isn't steel it's aluminum; that part I'm not too sure about. I've installed a lot of gas blocks, but no aluminum ones, so maybe someone with more experience than me can chime in about their reliability. Assuming everything is safe I'll put it on a barrel and put a few hundred rounds through it this weekend.
I'm good at a few things, but taking photos isn't one of them, so bare with me.  </a>" />

| Yes, I drilled through the bottom lug. I then drilled a bigger hole and threaded the hole for some 10-22 set screws. Tomorrow I'll do a couple of mag dumps and see how it holds up under some pressure. I'll also bang it around to see if it moves when doing so. I'll approach this from a skeptical view, hoping to be pleased, but expecting to be disappointed. |
|
First of all, I hope this is the right place to do this, but I think this is one of the cooler clones and since so few people can do this because of the flip-sight I thought it was.
OK, after a four hour range trip I've done some testing out the Colt knock of Flip-up front sight. So I attached the sight to a 10.5 barrel I'm getting ready to replace as shown below. I only attached it with the one set screw, I didn't pin it on.  </a>" />
Ammo: Monarch 55gr Steel Case. It's pretty under-powered stuff, I've had guns that just don't like it. My first SR-15 wouldn't shoot it very well at all, and this upper has struggled with it from time to time, I think it's the size of the gas port. Results: The first 5 shots didn't work. They moved the bolt back, but only half way. I didn't lube the bolt so put some lubrication on and switched out an H buffer for a regular buffer and the next 15 shots fired fine, though the bolt never locked back. In fairness I'm pretty sure this is an ammo gas port diameter issue, not a gas block issue. Next I did a mag dump with two mags. Other than not locking back the bolt it went just like it should. The barrel got hot, I stuck a meat thermometer in the barrel and it read 260, I don't know how good of a test that is, but I could feel the heat coming off of it. The gas block stayed on just fine and after the mag dump was still on solid with just the set screw. Personal Impressions: The block did much better than I thought it would, it didn't give me any major problems and worked just like a gas block should. I do think that if you decide to tackle this project that it needs to be pinned on with taper pins. I personally wouldn't worry about it being on a rifle like a Sam-r because they aren't really guns that you abuse. The problems I did have I think are primarily the ammo and the gas port diameter. If I were going to permanently attach this sight to the barrel I used today I would open up the port just a bit, but that is a barrel issue not an issue from the gas block. Finally, in a change from earlier in the week I would trust this gas block with some exceptions. I wouldn't trust it to run multiple mag dumps on full auto. It might work, and pinned I would bet that it would, but that seems to be pushing it. Being aluminum I'm also not sure how well it might do in a Lone Survivor style fall, but if you have such a fall I'm not sure that a gas block moving a thousandth of an inch to the left is really going to be your problem. Anywho, this was a fun project and just thought that I would post the results. |

The only thing I needed was the fuckin fsgb. If this becomes a "thing".....ya'll just remember who put this idea on the table lol |

Made a Few changes to my WOA - SDM-R. Decided to go with a PRI sight and also switched to the Griffin Comp. What a difference!
Not sure what its called now...... SDM-R MOD 1 ?????
I am REALLY liking these Mods! I will be running this baby hard this week on the Range. Look for more pics to come!

I paid $600.00 for mine  and it was used...I was also hell bent on putting one of these together too so depends on the buyer. A used one sold recently on the EE for 550.00.

I don't know...I am guessing $500 to $600 from what I've seen in the past. Personally, I am going to use a GG&G AR Bolt On Flip Up Front Sight Gas Block System has a substitute until I can find a deal on the KAC front sight. I still need to find a damn KAC FF Rail, too. These USMC SAM-R clones are a PITA to source the correct parts for! Here is the GG&G Front Sight. It'll work in a pinch. I am thinking of using the White Oak Armament SDM-R barrel. Anybody have opinions on that. |
| I think I've reached the point that if I want to build a SAM-R clone/near clone for the 2016 shooting season that I need to pick a "Plan B" front sight. Is there concensus or do we want to start another thread? I'm leaning toward a non-pinned version so that I can preserve the option for a pinning of a KAC unit if it ever comes available. But I'm open to others thoughts on that. |

The whole suppressed SAM-R thing really has to stop, it was never used in that capacity. Wikipedia is often incorrect, and is so in this regard. Same with the ARMS #17 mount for the bipod, it used a KAC Bipod Stud. Anyway, good luck with your build, William William |

Anyway, good luck with your build, William William Funny you mention that, I had the same discussion with a local dealer here over the weekend who said the same thing. You can see in my pics that I went with the standard birdcage and the KAC bipod stud. Still, a NT4 is on my short list of suppressors so I may use one on the SAM-R at some point but I'm leaving it as is for now. |
