TC Contender .45 Colt/.410 Ga. Choke Tube
These are precision reproductions of the internal choke tube that fit rifled Thompson Center .45 Colt/.410 ga. shotgun pistol barrels. If you've lost your original 45-410 choke tube, this one will replace it. (Note: This choke tube does NOT fit .357 nor .44 mag barrels.)
