Item Description

NO MAGAZINE SALES INTO NEW YORK CITY. CONNECTICUT RESIDENTS MUST FURNISH US A COPY OF YOUR CT ELIGIBILITY PERMIT OR AMMUNITION CERTIFICATE. Here is Tac-Cap's two shot extension tube with spring for Remington thread shotguns. It replaces a standard magazine cap on older model Remingtons, or current production 870P and recent production 1100P Police Shotguns. Manufacturer is a Michigan contractor. Tube construction is lightweight aluminum alloy, with checkered nurling and end cross cuts. Spring is steel compression type. Weight is only 2 1/2 ounces. It will fit old model Remington 12 gauge pump and semi auto shotgun manufactured prior to 1986 with no modification, including models Sportsman 12 pump and auto; 870 Wingmaster, 870 Police, and the venerable 1100. This tube extension will readily fit standard old model Remington 12 gauge shotguns with detent balls embedded into their barrel lugs; and whose magazine tubes hold 4 rounds of 2 3/4 inch shells. This replacement tube will bring magazine tube capacity up from 4 to 6 each 2 3/4 inch shells, and give a Remington a 6+1 capacity instead of 4 + 1 on 2 3/4 inch. It will yield similar results on 3 inch shells, from 3+1 up to 5+1, but very few of the older Remingtons were even made for 3 inch shells. It will not fit a Model 11, or a 31, or a 48, or a 58. Remington Shotguns with dimpled magazine tubes and magazine spring retainers that rotate into place must have their dimples removed and their main tubes modified. See the photos for the difference. The newer manufactured post 1985, 870s and 11-87s will require modification to their magazine tubes, since there are dimples inside the new shotguns' tubes that hold the spring retainer in place. The way we do it is simply Dremel down the two dimples and make sure the inside of the tube is smooth so that the shells will move along smoothly in the tube. Once a person does that, he cannot go back to the old shorter style; it permanently modifies the magazine tube of the shotgun itself. Carrying more than two shells in a magazine tube for hunting Federal status Migratory birds – doves, ducks, and crows – is a violation of federal law. In some states more than two shells hunting anything is a violation of state law. Installing one of these on an imported shotgun is also a violation of Federal Law if it makes the magazine capable of holding more than 5 shells. Finish is polished surface black anodized. Tube proper diameter is 1.125 inches; collar is larger. Overall length is 6 inches. Replacement pricing on kits like this is upwards of $100 in many places. We're offering the Tac-Cap II Magazine Extension kit in the photos, however, or one of its identical mates, for only $ 39.00 Not for sale to residents of New York City.
