I assembled a 12 upper and was going to need a new carrier since I bought a Monster bolt to go with my Group Buy barrel. I thought it was a good time to buy a new stripped carrier and add the RCA adjustable gas key. I have a 16 Carbine gas 6.5 Grendel which is over gassed. I decided this was a way to take care of both builds. The carrier from the 16 and new bolt is what Im using on the 12.
