Got a question for you AR guys. With all other things equal, (Buffer tube, and buffer tube spring), is running an M-16 bolt carrier group easier on the gun than an AR-15 bolt carrier group is? What I mean is, I swapped out the stock AR-15 bolt carrier group from one of my Bushmaster M-4's, and installed a Nickel Boron Coated M-16 bolt carrier group from Aries Armor. The gun runs fine. Both feeds and ejects beautifully. I'm thinking with the added mass of the M-16 BCG, it will be somewhat easier on the gun because it will slow down the cycle time.
Am I right or wrong? I'm asking because I have another BCM, M-16 BCG I'm thinking of putting in my other Bushmaster 20" rifle. I figure since I have the thing, why not use it? I bought it for an "emergency" spare. But I figure I'll run it and keep the original as a spare. I would rather not start switching buffer tubes and springs. Especially since what I've got already in there is working fine. What do you guys think? This is the M-4, and the 20" rifle I want to put the BCM, M-16 BCG in.
