Expect nothing less than professional grade weaponry from BCM. This Bravo Company Manufacturing Barreled Upper Receiver is built around a 41V50 chrome moly vanadium steel barrel. Using the Kino Configuration allows the sight radius to be extended on a shorter barrel without creating cycling issues. This is accomplished by mounting the FSB as close to the muzzle as possible while a low-profile gas block placed further back performs the actual work of the gas system.This configuration may enjoy better accuracy using iron sights with a longer sight radius and the use of a longer handguard without sacrificing reliability.
