This quality lower parts kit excludes the two most commonly upgraded components - the grip and the trigger assembly (fire control group).
This is the perfect kit for premium builds that include premium triggers like the AT3 Tactical 2-Stage Trigger. The kit contains quality, mil-spec parts and provides you with the flexibility to spend money on the parts you want - and none of the extras that will sit in your toolbox.
New Color Options!
We've added the option to get a Pro-Builder kit with all the parts you'll see outside your gun in matching Cerakote! We've included a handy guide so you can make sure you're getting the right color for your build. Naturally, these match with all of AT3's other Cerakote AR parts.
