Thinking about doing another "tribute" rifle, ok, clone. I want to have a SAM-R built. Anyone know what year PWS built them and if any of them had the gas blocks secured by set screws and milled barrel flats or if they all used tapered pins? I only wonder this because if they were based on PWS rifle team service rifles, would they have used the barrels they had on hand to build the first ones, which would have probably had screw flats. Any thoughts?
- Thread starter eodcam
- Start date
I'd try arf.com on that one. Never seen a post on SH about a sam r build. SDMR, MK 12 mod 0, 1 I have seen clone builds on here with specs. I think what stopped me was the front sight assembly specifically where to find.

Appendix A: Rifle configurations
The following pages show lists and figures of the configurations of the 5 SAM-Rs and 3 M-16 A4s that we used for this testing. The SAM-Rs are numbered for reference to table 1. We assumed that there was no difference between the rifles’ performances. However, the precision values from SAM-R 1 were found to be significantly worse (by more than 20 percent) than the other SAM-Rs (t-test, p < 0.03). The figures also show the optic used with each SAM-R. All SAM-Rs were built to the 2-MOA specification. They were new, with no more than 150 rounds through them. They were fitted with Harris swivel bipods HBLM-S and A.R.M.S. quick release bipod mounts.
SAM-R 1
• Olympic Arms FIRSH free float tube
• Colt heavy barrel, chrome-lined, 1:7 twist
• No flip-up sights
• KMC scope riser rail
• KMC low profile scope rings
• Standard flash hider

Awesome! Thank You! This helps make some of the info I've been finding make more sense! Thanks Again!
I always thought the SAMR had a knights flip up gas block/sight
In the End I believe it was.
I own a rifle that I built the lower. I bought a BCM 410ss 16" upper.
Specs on the upper
Features
M4 Feed Ramp Barrel Extension
M4 Feed Ramp Flat Top Receiver
T-Marked Upper Receivers
1/8 Twist Rates
5.56 NATO Chamber (USMC SAM-R)
410 Stainless Steel
HPT (High Pressure Test) Barrels
MPI (Magnetic Particle Inspected) Barrels
