In any event- discussing the technicalities of devices which are flat-out illegal for essentially everyone (excluding the military and specialized police divisions) in an online forum oriented at Canada/Canadians is just plain asking for trouble- for everyone.
Agreed.
However...
The item he describes is not a problem. Muzzle BRAKES are fine. The problem is that he has misinterpreted the devices function...I'll mark that down to the widespread misuse of terminology prevalent on the various airgun forums.I like the long 4 or so in. brass muzzel brake with front site post on it and holes around that the tops are enlarged,,mailed a dealer down here and asked if they could order one on a request from me
