If you are not familiar with AERO PRECISION products, here is a quick video on their lowers. The parts kit that is included with this lower is specifically for this lower.



Our AR15 Gen 2 Stripped Lower Receiver is the perfect base for your custom AR15 build. Machined to mil-spec dimensions, our lowers work with standard AR15 components and ensure the highest quality with a correct component interface.

Gen 2 Improvements

  • Upper Tension Screw - Allows users to fine-tune the fit of the upper and lower receiver through the use of a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
  • Increased Magwell Flare - This allows for the easier insertion of magazines and provides a sleeker look.


  • Stripped AR15 Lower Receiver, Gen 2
  • Nylon tipped tensioning set screw
  • The rear takedown pin detent hole is threaded for a 4-40 set screw, no need to fight detent and spring when installing buffer tube and castle nut. Aero Precision Lower parts kit has this screw included.
