Questions & Answers
Will it work in a DPMS 308 rifle? Expert Answer

It will function if you have a full-auto compatible bolt carrier group, however it may require you to change buffer weights to get it to cycle properly.

dose this come with a bolt carrier do i need a special bolt carrier Expert Answer

This does not come with a bolt carrier group but it does not require a special one, it will work with most standard bolt carriers.

Helpful Positive Review My Favorite Trigger by Kumar, Verified Owner, November 2, 2017
I've Only had a few 100 rounds through this trigger, but have not had any issues what so ever. Best upgrade on any AR by far. Easy to use and the install is straight forward and easy. Only down side is the price, but trust me It's worth it.
