This video provides a product spotlight on the Brownells BRN-180SH™ complete upper receiver assembly in .300 Blackout. The "SH" designation signifies its optimization for suppressed shooting, featuring a unique three-position adjustable gas block that allows for complete gas cutoff for maximum sound suppression. This feature, combined with a larger, ergonomic charging handle, offers a quiet shooting experience similar to a straight-pull bolt action, making it ideal for hunting applications like deer and hog harvesting. The upper is compatible with mil-spec lower receivers and BRN-180® dedicated lowers, supporting folding stocks and pistol braces due to its internal operating system. It comes with a 10" barrel and can be used for AR pistols or SBR builds with an ATF tax stamp.
