In Response To: Squad Designated Marksman Rifle (LeagleEagle)

I can tell you much about the Marines SAMR (Squad Advance Marksman Rifle) that was alluded to in the article. Since I was the original designer of it back in 1996, it has changed very little in the last ten years and has proven to be an incredibly successful weapons system.

The basic platform is a standard M16A2 lower with an M4 flat-top upper. The feed dynamics of the M4 upper are superior to the A4 upper. The barrel is a 1 x 7 Krieger stainless barrel procured from Compass Lake as a set; barrel, bolt and barrel extension. Compass Lake does the chambering (NATO) and headspaces the bolt to it. Contrary to the article, the barrels are blued at the PWS shop; however, the finish is not very durable and wears easily so the majority of the existing SAMR’s look like they have unfinished barrels. The rail system is the KAS RAS, a big mistake because it works loose and several have been reported broken. We had to modify the rail locking nut with a set screw to keep it in place. If I was to do it again, I would use the Larue Tactical 13.2 inch rail system as it locks solidly in place and completely covers the gas tube. The front sight is a standard flip-up that is integral to the gas block. The bipod is a Harris swivel bench rest model with Pod-Lok. We built the SAMR the same as the NM M16A2’s meaning the rifle is set up using the same exacting standards we used in building the NM guns. Utilizing MK 262, we were getting sub-minute groups out to 800 yards.

Anything out there close or similar in strength and looks to a KAC 12 free float, seems like they don't exist....
