This video provides an overview of the Colt 6920 AR-15 lower receiver, now available for individual purchase through Brownells. The instructor highlights its mil-spec construction, including 7075 T6 aluminum, hard anodizing, and a four-position stock. Key features for clone builders and collectors are discussed, such as the 'Colts Law Enforcement Carbine' markings and compatibility with standard aftermarket pins since mid-2008. The presence of a full shelf to prevent auto sear use is noted.

This guide details a practical technique for replacing an AR-15 takedown pin, even when the castle nut is staked, without disturbing the staking. It utilizes a small precision screwdriver to manage the detent and a longer pivot pin as a slave to facilitate the swap. This method is ideal for upgrading components like enhanced pins.
