At the end of the day, there’s nothing wrong with MIL-SPEC. It gets the job done, after all. Still, why would you settle for the bare minimum acceptable standard when you could elevate your build with something better? The MKII GGP-S series receiver set is just what you’re looking for. Precision machined to exacting tolerances with a host of upgrades over standard receivers, the GGP MKII Billet AR-15 receiver set is the ideal way to start your build.

A proper MIL-SPEC lower receiver’s dimensions can vary over .005″ or more from one receiver to the next. This is fine for a military rifle, but these tolerances can stack up, impacting parts compatibility, fit, and function, especially when using aftermarket components. By comparison, the MKII Billet AR-15 receiver set is machined to exceptionally tight +/- 0.001″ tolerances, allowing for incredible consistency. To further increase accuracy this lower features a nylon tipped tension screw, ensuring your upper and lower fit together without rattle. For enhanced convenience, the bolt catch and takedown pin are threaded for fast and easy installation. Even better, the lower is machined for an ambidextrous bolt catch release.
