This guide details the process of modifying AR-10 platform lower receivers, specifically LMT MARS-H and KAC SR-25, to accommodate an AS Designs Arcfire FRT. The host, demonstrating high mechanical expertise, explains that the internal shelf of these high-shelf lowers requires milling to provide adequate clearance for the FRT lever, a crucial step for reliable function. The video contrasts this with the easier integration of FRTs in 5.56 platforms like the LMT MARS-L.

This guide details the installation of the PDQ Ambi-Bolt Catch, a component designed to enhance the ambidextrous functionality of the AR-15 platform. The video emphasizes that while the Magpul BAD Lever is a simple attachment, the PDQ requires a permanent modification to the lower receiver. Expert instructor Ian McCollum highlights the safety concerns with controls inside the trigger guard and demonstrates the significant speed advantage gained with the PDQ lever during reloads.

This guide details the installation of the PDQ Ambi-Bolt Release for AR-15 platforms, as demonstrated by Military Arms Channel. The process requires permanent modification of the lower receiver, including cutting a trough and removing internal fencing. The PDQ allows for ambidextrous bolt manipulation using the index finger of the shooting hand, significantly improving reload and malfunction clearing times. Expert instruction highlights the need for precision during the modification process.
