Brownells 75th Anniversary - A Shooting Heritage

Unique Design For Competition Use

External “Special Purpose” Choke Tubes made from high tensile strength e.d.t. 150 carbon steel to withstand the higher pressures created by large shot and the constant pounding of competitive shooting without bulging at the threads or splitting the barrel. If a tube does fail, simply remove and replace with another. Lead Shot Only! Not For Steel Shot! Undersized I.D., open up to match customer’s needs. WARNING: Must not be used as sold. MUST be opened up. Gun damage or shooter injury may occur if constriction is too tight for the shot size and type being used.
