Funshoot,
Welcome to the dark side!! Thought I love my AR's, don't let the thought of recoil scare you away from the M1A. It is definitely more than the AR, but it is more of a 'shove' than a kick. Practice ammo, the edge definitely goes to the AR, but if you aren't reloading, the good stuff is expensive for either one. Also, as far as other uses (hunting, etc) the M1 is slightly more versatile IMHO, however, I will NEVER give up my AR's or my M1.
Again, in my opinion, value of muzzle break lies mostly in the 'cool' factor. Personally, I do like the look, but not the function, so I have the RRA fake breaks, or nothing.
Also, if I am not mistaken, I think the DCM Bushie has fore end weights under the handguards, so they could be removed, but double check me on that.
