The Aero Precision AR15 Lower Parts Kit with MOE SL is a complete mil-spec fire control group and grip assembly designed to get your AR15 build moving forward without hunting down parts piecemeal. Whether you're assembling your first rifle or your tenth, this kit covers the trigger group, safety, bolt catch, takedown hardware, and grip in one go—saving time and ensuring all components meet military specifications for reliable function.
What sets this kit apart is the inclusion of Magpul's MOE SL grip and MOE trigger guard, both in Black. The MOE SL grip is slimmer and lighter than full-sized alternatives, making it a solid choice for shooters who want a clean, no-nonsense ergonomic package. The trigger guard follows suit, maintaining the same design language while staying out of the way during operation.
Assembly-wise, you get a tried-and-true mil-spec fire control group—hammer, trigger, springs, pins, and disconnector—plus all the small parts that often hold up a build: detents, springs, bolt catch components, magazine catch hardware, and even a 4-40 set screw for threaded takedown pin detent holes. Nothing exotic here; it's straightforward parts that do their job quietly.
This kit is designed to work with Aero Precision AR15 Gen 2 lowers and any mil-spec AR15 lower receiver, making it a reliable choice for builders who want simplicity and compatibility without fuss.
