This guide details the process of converting an M16A1 lower receiver into an M16A3 configuration, a rifle primarily used by the US Navy. The key technical difference is the M16A3's full-auto fire control group (Safe-Semi-Auto) compared to the M16A2's three-round burst. The video highlights that FN Herstal manufactured many of these rifles for the Navy after Colt faced production issues.
This Brownells video features the "Hand-Firing Mechanism Mk II," also known as the Sedgley Glove Gun, a rare single-shot pistol chambered in .38 S&W. Developed for the U.S. Navy during World War II, it was intended as a self-defense contact weapon for Seabees who might not have time to draw a traditional pistol. The glove gun attaches directly to a work glove for immediate access. The video, hosted by Brownells Gun Techs Keith Ford and Steve Ostrem at Rock Island Auction Company, highlights the unique design and historical context of this unusual firearm, noting its limited production of 50-100 units and showcasing a well-preserved example.
