Also, speaking of recoil and comparing a AR-15 to a shotgun... The shotgun is going to have a lot more recoil sure, but, that .223 is going to travel a long ways. I spent the $100 to get a Knoxx Spec Ops stock and it was worth every penny. It doesn't change the muzzle pull but I put 50 rounds though her today and I can't even tell. It's worth it for sure.
What kinds of loads were those 50 rounds?
