SAM-R barrel with Service Match Heavy Contour
BCM® SS410 Barrels

To give the shooter the best accuracy this BCM SAM-R barrel has a service match heavy weight profile and a rifle length gas system. (410 stainless is a harder and more corrosion resistant than the conventional 416 stainless found in most barrels.)
Requires the use of the .750 gas block or front sight base.

    Perfect fit for my Anderson upper. Only have 40 rounds through it so far and no scope. Can't attest to accuracy yet but the quality of this barrel is top notch.

    most accurate barrel I've ever shot

    1/2 MOA at 150 yards, and trust me when I say that I am not the best shot. Great barrel.

    BCM 20" SS410™ SAM-R Barrel with Rifle Length

    Perfect build for my M16A4 style (DMR), very high quality Stainless steel barrel, little extra weight on the barrel but it's a perfect build for a designated marksman rifle.

    This barrel went to my first AR-15 build and I got to say, I am insanely impressed with it. Did a range test on it and got some really great results! Distance was 500-600 yards away. This barrel is amazing, would recommend.

    Best Barrel

    This is the second I've purchased. The first is on my dedicated varminter. Shoots MOA with any quality factory ammo I've tried, but the Varmageddon 62gr HP load shoots 0.4" groups. Can't ask for more than that. Totally worth the $.
    My son went with another barrel costing about the same, and now is getting this one.
    Save time, save $, buy this barrel.
