The Advanced Technology Int. Strike Force Shotgun Forend in Black is expertly crafted to fit a variety of 12 GA shotguns including models such as the Mossberg 500 535 590 and 835 as well as Maverick 88 Remington 870 and Winchester 1200 1300 and SXP shotguns. For compatibility Mossberg shotguns must have a 6 3/4" slide action tube and Maverick shotguns will also need the addition of this specific Mossberg slide action tube. Notably newer Mossberg shotguns particularly those manufactured after 2006 should be examined to confirm they have a removable forend. For Winchester forend tubes with a minimum length of 6 1/4 inches are necessary to use this product.This shotgun forend is enhanced with a tactical Picatinny Rail package which includes both a left and right 2" rail offering seamless installation for preferred accessories. The design is not only robust but also incredibly lightweight and it proudly bears the mark of quality as a product made in the USA. Textured for an optimal grip the forend comes with blank inserts for moments when the rails are not in use.
