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

Thanks to you folks at AT3! I'm a first time buyer at your site and the ease of ordering and speed of delivery was astounding.
I ordered the NP3 lower parts kit. I'm so pleased with the quality and value. The feel on this trigger is like I spent 3x more $. Nice work and what a great piece of "candy " in the set was the ultra solid adjustable pistol grip.
I'll be back for more!
Thank You AT3 TACTICAL,
Good fit and function will purchase again from at3.
Shipping is prompt & Great products!!
Arrived quickly installed easily. Haven't tested it yet
Purchased the kit to upgrade my Bushmaster's trigger, trigger guard, and grip. Parts fit perfectly and was easy to install per AT3's installation videos. Trigger guard was a bit of a puzzle initially as the allen screw was not evident at first and the video didn't include the detail needed to install the guard properly. A magnifying glass helped me see the allen screw was in the hole already and I just needed to tighten it into place. Now, with the adjustable grip, the rifle feels better to me and I have some spare parts. Good deal on sale, free shipping, and fast. Recommend this kit to others with an AR.
