This guide details the installation of an AR-15 buffer tube using the LAW Tactical LAT and Geissele Reaction Block. The process ensures proper alignment of the receiver extension with the lower receiver before torquing the castle nut to 38-42 foot-pounds. This method is recommended for users who already own a Geissele Reaction Block to prevent misalignment issues.

This video details five common AR-15 build mistakes. It covers accessory interference with the gas block, improper gas block alignment leading to cycling failures, incorrect castle nut torque (40 ft-lbs recommended), over-lapping the upper receiver during lapping, and incorrect buffer tube depth affecting the buffer detent. Addressing these prevents accuracy issues and ensures reliable function.
