  4. accurate. 5 Star Review

    Posted by on 23rd Jul 2019

    I’ve free floated this barrel in a MI combat rail, and it achieves consistent near MOA performance with Federal xm193 55gn. 1 7/8” at 200 yards, 3 1/4” at 300 yards, and 4 1/2” at 400 yards ( consistent 5 shot groups). Top quality performance for plain military ball nearly makes hand loading unnecessary. A true testament to quality.


  5. Exactly what I needed 5 Star Review

    Posted by on 3rd Jun 2019

    I used this to complete an old demilled M16A1 parts kit. For this purpose it is perfect. It functions reliably and is more accurate than me with iron sights. To those asking about why there are no cuts for taper pins the answer is because it is not standardized exactly where those cuts go. New FSBs come without holes and old parts kits FSBs come with holes that are not going to be in exactly the same place as any other given FSB. All you need to make the cuts is a drill press and a taper reamer for making it tapered after drilling. I recommend putting the reamer in a tap wrench and reaming by hand rather than using the press. You will need to get oversized pins for building a demilled parts kit that already has holes in the FSB.
