12ga only, 1 in 34 twist. Chokes extend out of the muzzle approximately 6" (15 centimeters) and depending on choke system will be approximately 8" overall length. The CT II system will fit nearly all Hastings brand wadlock barrels.
NOTE: NOT FOR USE IN SEMI-AUTO LONG RECOIL OPERATED FIREARMS, WHERE THE BARREL MOVES INTO THE RECEIVER (BROWNING A5 AND SIMILAR). SEMI-AUTO GAS OPERATED AND SHORT RECOIL FIREARMS (BENELLI) ARE OK. AS WITH ALL CHOKE TUBES, IT MUST BE TIGHT AND THE OWNER NEEDS TO CHECK AFTER FIRING.
