Have Questions About this Product?
Havent had time to fire the weapon, but dry firing this 2 stage trigger feels amazing. Can't wait to take it to the range. Installed the 2 stage in my 300 blk pistol and replaced the factory trigger in my carbine to the 1 stage nickel teflon trigger. Both feel great.
I always wondered why my mil-spec trigger was so bad. Now I know. The take-up before the break is perfect for target and hunting. The reset is short and audible. It would be nice if it were offered in a flat face as well, but that's just a suggestion, not a complaint.
I was considering a timney or geissele trigger until I came across this, now I couldn't justify the price.
There was one problem with the kit. The detent for 'safe' on the selector was too deep, and would not allow me to rotate it back to 'fire'. I called up AT3, and I had a new selector in 2 days, which functions perfectly. Excellent customer service!
I will be returning to order more parts and accessories in the future, including more of these triggers for all of my future and current ARs.
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.
