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.

    most accurate barrel I've ever shot

    Posted by Sean Keeley on Oct 27th 2017

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

    Best Barrel

    Posted by A Bennett on Oct 13th 2016

    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.

    Exellent quality

    Posted by Kyle Russo on Apr 26th 2016

    I was very impressed with the quality of this Barrel. The fit and finish were perfect. I have not yet had a chance to shoot it, but reading the other reviews, I have no doubt that it will be a tack driver!

    Really an amazing barrel. I put this barrel on my first build and I am amazed by the performance. After dialing in I was grouping shots to around 1/2 moa with 62 grain Fiocchi ammo. I am an amateur in all sense of the word, and was elated to have a rifle this accurate. I will definitely use a Bravo barrel on my pistol build!!

    Excellent Barrel

    Posted by GREGORY MUFFLEY on Aug 25th 2014

    After 9 months and approximately 900rnds, I couldn't be happier. I have achieved as good as 1/4 MOA with handloads at distances beyond 100yds. Even factory ammo has been MOA or better.
