I really don't understand the concern with being muzzle heavy or unbalanced. The A2 stock that came on standard issue M16s with a 20 inch government profile barrel are no heavier than an adjustable carbine stock. As I said earlier, I am using an Ace skeleton stock which is lighter yet and it still is not muzzle heavy and balances quite nicely and that is with a 20" heavy barrel and aluminum rifle length free float tube. Barrel is fluted under the handguard. I just weighed the A2 stock that I took off to replace with the Ace and it weighs 13.2 oz. I can't imagine a collapsible stock being enough lighter than that to cause a muzzle heavy concern.
