Brownells 75th Anniversary - A Shooting Heritage

A Lower Parts Kit Designed for Aero Precision's M4E1 Lower Receiver

One of the most-popular furniture kits for AR-15 builders is Magpul's line of MOE grips, buttstocks and handguards. In fact, when buying lower parts kits to finish a build, most AR owners will toss the A2 included in an LPK for a Magpul. So why not buy a parts kit that includes the Magpul MOE Pistol Grip with it? Enter the Aero Precision AR-15 M4E1 Lower Parts Kit.

This lower parts kit is designed to build Aero Precision's M4E1 lower receiver, and as such, it does not include a trigger guard, as the guard is integrated into the Aero M4E1 lower receiver. Here's what you'll receive in this kit:

  • Magpul MOE Grip in Black or FDE
