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.
