Experience the difference a 2-Stage Trigger makes in your next build.
AT3 is pleased to offer the dependability of our Pro-Builder Lower Parts kit with the new 1005 Tactical 2-Stage Nickel Boron Trigger. With a 4.5 lb total pull weight and a durable Nickel Boron finish, this trigger ensures a smooth pull and crisp break every time you squeeze the trigger.
The two stages of this trigger consist of an initial 2 lb pull that brings you to a “wall”, where the hammer and trigger are set to break for the shot. After that, it’s only a 2.5 lb pull to fire, helping you to make accurate shots with short resets in between.

Have Questions About this Product?
I've built dozens of AR15 rifles and i have never seen a better lower parts kit than AT3's lower parts kit with 2 stage tactical nickel boron trigger. If you have built as many ar's as I have, you know lower kits are not all created equal. its not just the fact that the trigger group is better than any other trigger in its price range by far, the other lower parts are absolutely Mil spec. that can not be said of all lower parts kits. A precision trigger and mil spec lower parts kit, at this price is an unbelievable value.
Really pleased with this kit. Especially the trigger. This is my 1st AR 15 and could not be happier with how the 2 stage trigger fits, feels, and functions. Years of long range bolt action rifles had me skeptical but this trigger puts the 6.8 SPC, 22" heavy barrel, side charge right up there with my favorites. Thank you for making it available
I picked this up for a good price with a LPK on a Daily Deal... Always been wanting to try a 2-stage trigger, I figured this was the time...
Installs like any milspec trigger, but that is where the similarities end... I was super impressed with the fit and finish of this FCG... plus coming in around $100 with the LPK, you cant go wrong. I like it better than my 3lb single stage
I put this into a Noreen billet lower and matched it up with the AT3 Tactical SPEAR Upper combo in Magpul Stealth Gray, topped it with a midrange 1-6x24 scope..... Its way to nice to be shooting 7.62x39... It looks good, feels good and shoots even better...
Thanks again AT3!
