I was with 1st bn 4th marines - 0311 from '02 - '08. I went to iraq in 03 for the invasion- operation Iraqi freedom 1 and then operstion iraqi freedom 2 in 04. When we came back from iraq after tour 2. I went to the first designated marksmen course in '05. I was a 2nd award rifle expert E4 corporal squad leader green belt instructor.
The rifle I was issued for the Designated marksmen course was a m16a4. Acog 4x scope. Harris Bipods. FSB 20" Barrel w normal compensator. W 3 point sling. It had Knights free floating handguard w covers. Knights foward grip. A2 butt stock. " West coast Sam-R " The rifle range for the designated marksmen course was 500 yard course like any marine rifle range. They pushed us way back ontop of a burm at 700 yards. I hit the target at 700 with my rifle. The weapons I carried during oif1 - m249 sub automatic weapon " saw gunner " for awhile. Then m203 m16a2 and normal m16a2. Positions changed as we grew w more marines. In oif1 03 invasion of iraq. Some corporals in my squad who were rifle experts got m16a4 w acogs and knights free floating hand guard w knights pistol grip.. no bipods yet.. a2 stock.. the extra acogs we had went onto m16a2 w carrying handle mounts. In oif2 I was a fire team leader. I used a m16a4 w acog no bipods setup from oif1 for the whole 2nd deployment. Semper fi " west coast Sam-r " |

I never paid much attention to the SAM-R, but years ago I had heard of a "west coast" SAM-R and didn't realize it was legit.
Early on in the thread mnrideshonda posted basically a basic m16a4 w/ 2.5-8 on it. Was that ever in the wild like that? |

Forgive my ignorance, but I thought the SDM-R had a DD rail and A2 FSB? And West Coast SAM-R is just an M16A4 with a Leupy MK4 2.5-8?

At the time the goal was to equip one riflemen per squad with an optically sighted rifle, growing out of a request form the East Coast Marine Corps to reequip the 4th Marine Expeditionary Brigade’s (Anti Terrorism) Marine Corps Security Force Battalion’s DMRs with SAMs. West Coast units since they where way down on the fielding list timeline for SAM issued the first A4s they got with some TA31s bought with an urgent need statement as make do SAMs. |

I think Samsondog is the guy to answer that question. I didn't go quite that far down the clone rabbit hole with mine and just used a Colt AR-15A4 lower. I also am using a non-clone correct, but period correct 3.5-10x Mk4 scope because fuck it my eyes are older now. |

I do believe NT4s did get used, quite certain I have seen photos of a SAM-R with one mounted, possibly from a Sniper or STA platoon, painted as well. The bulk would have been A2 though.

The fact that the S&B 3-12x got photographed in the same room as the SAM-R is enough of an excuse for me to want one on it.
But to my original question; machining that pic gas block... surely there's someone here who can do it. Or at least someone here who knows someone who can do it. |

I had an original, but sold it last year:
   The SAM-R's had about 10 prototype PWS gasblocks, 20 KAC Gen 1 gasblocks and 70 KAC Gen 2 gasblocks. There were a total of 100 rifles. The SAM-R's never had the KAC Gen 3 gasblock, those were used on SR16's and SR15's. So, technically every single clone in this thread with a Gen 3 isn't clone correct, but it's as close as you can get unless you find a Gen 1 or Gen 2 ($$$$$). Here's a comparison between the 3 KAC FSGB generations (the top 2 are on SR16 uppers). Top to bottom: Gen 3, Gen 2, Gen 1  The barrels were marked in 2 lines: CLE 1-7 2-03 USMC KRIEGER 1H1H9 The above 2-03 is an example of the date marking. Since they were built early in 2003, the first line of markings will be the month and year that upper was build, such as 2-03, 3-03, 4-03, etc. CLE is Compass Lake Engineering, 1-7 is the barrel twist and 1H1H9 is CLE's cage code. The barrels also had a number stamped on it that represents that rifle out of the 100 that were built. A matching number to the barrel was also hand engraved on the bolt. The last barrel marking added was the PWS-P proof stamp, it was struck between the legs of the FSGB. Add all these markings to your build if you want, but the only one that really matters is the PWS-P stamp, since it's visible on the rifle. Hope this info helps! |

The actual gas block portion on the Gen 2 & 3 look forged, but the Gen 1 looks milled. If the Gen 1 is in fact not using a forging, it doesn't seem like it would be too terribly complicated for KAC to make a run (lol) or for a competent machinist to make a faithful reproduction. |

There are people with better relationships with KAC than me who would better suited to ask the question. Are there any KAC dealers or reps that would be interested in coordinating an effort like that? Is Ayan still around? I know it's a long shot, but worth asking before sinking time, brain power & resources into a clone of the PWS gas block. |

Quote HistoryOriginally Posted By HaveBlue83: as a machinist, id want to clone the gen 1 first. the other two would require sand casts , then machining. the early pws is also all machined so easier. KAC's FSGB looks to be made from different materials. It looks like the block is steel and the folding sight is aluminum. Where would someone who wanted to do a repro even start in terms of getting KAC's permission (or indifference)? I'm not advocating doing anything nefarious regarding KAC's IP, just curious of the hoops one would have to jump through so that everyone's happy. The Gen 1 KAC looks simple enough, but the PWS block is definitely the safest play for reproduction in terms of manufacturing and IP concerns. Personally I don't really care which. It's a function over form issue. A GB that's taper pinned with a bayo lug that provides the proper sight radius will work, whether a KAC or PWS repro. |

It would be for my rifle, for me. like i did with sleeving a umarex one with steel at the gassing areas. some things u hust gotta go get a bridgeport for. and a $1500 gas block is more than a used J1 head mill AND SOME TOOLING costs. keep that in mind.

Using the following reference, I created a CAD model. I am 99% sure the dimensions are correct, but I have no way to verify without making a prototype.
My background is in CAD, but I have no professional machinist experience. Any advice from resident machinists is welcome. On material selection, I initially thought 4140, heat treated, bead blasted, & phosphate finished would yield desirable results, but after reviewing the drawing on the SOCOM gas block, I'm weighing whether or not 416 SS (heat treated, blasted, & nitrided) would be a better selection.

Since the SAM-R/SDM-R thread has morphed into mostly the "SAM-R Show," let's balance it out a little and see what sort of SDM info is out there.
Does anyone have any info about who originally produced the barrels for the SDM-R's that got deployed as part of the Warfighting Experiment? As I understand it they should be 20" 1/8 twist, 12 flute barrels made from Douglas blanks, but did CLE originally spin/flute them or was it someone else? Also, any info on how they were marked or finished? Were they blued, painted or something else? One of the older photos of an SDM that was shared with a NF(?) scope on it showed some pretty heavy finish wear forward of the FSB, but I can tell if it looks more like rubbed of bluing or if it's flaked paint. My low confidence vote is paint. One other, probably easier question to answer is, for the standard FSB that's been set screwed on instead of pinned, did they need to mill flats for that or do they just crank the grub screws in and it holds well enough on the rounded contour? I have the same style gas block on my NRA highpower upper done by CLE, but I can't tell without taking it off and I don't want to ruin my zero.  |

Quote HistoryOriginally Posted By orpheus762x51: Using the following reference, I created a CAD model. I am 99% sure the dimensions are correct, but I have no way to verify without making a prototype. My background is in CAD, but I have no professional machinist experience. Any advice from resident machinists is welcome. On material selection, I initially thought 4140, heat treated, bead blasted, & phosphate finished would yield desirable results, but after reviewing the drawing on the SOCOM gas block, I'm weighing whether or not 416 SS (heat treated, blasted, & nitrided) would be a better selection. https://www.ar15.com/media/mediaFiles/305821/block_png-2091456.JPG https://www.ar15.com/media/mediaFiles/305821/Screenshot_20210913-131540_DuckDuckGo_jp-2091457.JPG https://www.ar15.com/media/mediaFiles/305821/Screenshot_20210913-123836_DuckDuckGo_jp-2091460.JPG https://www.ar15.com/media/mediaFiles/305821/Screenshot_20210909-152855_Drive_jpg-2091462.JPG @HaveBlue83 I got a request for you ^^

I’m not positive on who made the barrels from the blanks, or if the barrels had flats for the FSB screws. But I can tell you the 3ID SDM-Rs definitely had painted barrels that flaked over time. Kicking myself for not taking more pictures back in the day, though. But your High Power/Service rifle barrel almost certainly has flats for the FSB screws. |

Did you have experience with them in the field or just in passing? |
