Just an opinion. The best accessory I ever got for my AR, was the 22LR bolt-carrier adapter. About $200 (bolt carrier plus 2 magazines for about 30 rounds each of .22LR). The AR-15 is 5.56mm or .223 and the .22LR is approx .222; so it's not going to win any awards for 22LR accuracy; but the cost savings is phenominal.
Just don't rest your rifle on the magazine, and it will rattle off .22LRs as fast as you can wiggle your finger. So much fun.

Do they bounce in the barrel causing wear?
