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! Tru-Choke™, Rem™Choke and Win-Choke®-style tubes with very tight constriction for tightest patterns with #10 lead shot. WARNING: Do Not use with shot sizes larger than #8 lead. Do Not use with steel shot.
