Elevate the performance of your build with the AT3 Enhanced NP3™ Lower Parts Kit. 

This premium AR-15 lower parts kit provides significant upgrades to some of the most critical parts - the trigger, pistol grip, and trigger guard.

The Enhanced NP3™ trigger assembly removes grittiness and provides a cleaner "break", while the X-Tech ATG™ adjustable grip allows a configurable grip angle to suit your shooting style. We also added an enhanced trigger guard that provides extra room for gloves.

Enhance Your AR

  • The Enhanced NP3™ trigger assembly features smooth, precision-machined engagement surfaces and Nickel Teflon coating. The resulting trigger is functionally similar to a standard mil-spec fire control group, but with noticeably cleaner, smoother, and more consistent operation.

  • The X-Tech ATG™ Grip easily adjusts to each of the three most popular industry proven angles (17, 25, & 33 degrees). Subtle finger grooves, texture, and back-strap optimize comfort and control

  • The enhanced trigger guard that provides extra room in the trigger area, critical to shooting with gloves, or for those with larger fingers
