I have a couple of questions. The first..I just bought a new rifle and this is in the description..Can anyone tell me about the break? "Thunderbeast CB Series 5/8″x 24TPI Thread Over Suppressor Ready Brake." And next.. Is it really worth all the paper work? I have a class 1 FFL and that was a hassle! Can I just own one without upgrading to a 3? Thanks.
