Item Description

NOT FOR SALE TO CIVILIAN RESIDENTS OF NEW YORK STATE. Restrictions apply on high capacity shotguns in two jurisdictions, so please read this entire ad carefully before bidding or offering to buy. This listing is for ONE Magazine Tube Extension Kit with clamp. Combine with any total of any 3 non gun non ammo items, and shipping is Free for the entire order, lower 48. Here’s is a magazine extension kit that will turn the Mossberg 835 into a truly lead slinging machine. Manufacturer and warrantor is Choate Machine Tool of Bald Knob, Arkansas. We’ve been selling Choate tubes now for 40 years. Construction is welded one piece steel tube with threaded cap assembly and thick polymer spring nose, steel spring, steel clamp assembly, and high visibility orange polymer shell follower. Gunsmithing is not required, only enough sense to assemble and follow instructions. Where a standard model 835 Pump Mossberg holds 5 each 2 3/4 inch shells in its factory magazine tube, attaching one of these ups that capacity to 9 in the pipe, yielding 9+1 capacity on 2 3/4 inch shells. For 3 inch shells, make that 8+1; and on 3 1/2 inch shells, 7 + 1. The +1 means one in the chamber. With steel shot, then, the equivalent firepower on 3 1/2 inch shells is similar to 900 rounds of .22 caliber projectiles with a fully loaded shotgun; and about 500 round equivalent of #4 Buck, about .22 caliber, with lead loads. This apparatus will only fit Mossberg shotguns that have a detachable magazine cap, including models 835, 930, 935, 9200, and even 590. It will Not fit a model 500 or 535 because those have a closed end magazine tube. If the barrel is not at least 26 inches, muzzle blast will wear the finish because this tube will protrude past the muzzle. Some of our photos show it along side an 835 barrel that is not included, of course. Replacement pricing on similar, and no better, equipment from Tac-Star approaches $100 for a set like this. We’re offering the Choate CMT-02-04-20 set in the photos, however, or one of its identical mates, each for only $ 49.00. Not for sale to civilian non dealers in New York, or any jurisdiction where shotgun magazine capacity is limited to 7 rounds for civilians. Connecticut buyers must furnish us a copy of your State Issued Eligibility Permit or Ammunition Certificate, per P.A. 13-220. Any ammunition, firearms, or personnel showing in any of our photos are Not included.
