The use of that muzzle break might on a boly action rifle might get the felt recoil almost on par with a .22cal rimfire. I will be curious as to how the reliablity holds up with those multiple recoil buffer springs in teh upper reciever but conversion kits for an existing Barrett M82A1 seem like a good idea. Besides a coversion kit is not a new firearm as the reciever is already legal in most states, not CT but nothing says I can not have one in some different state provided I legally aquired it.
I am at this point wondering where one could get ammunition for it.
