Now you, the airgun hobbyist, can attach your favorite accessories to your .22 cal. airgun. This Steel Breech kit not only has a superior look, but it alleviates the need to purchase separate parts. With all-steel construction, it provides durability which in turn may improve your accuracy. With just the use of the two hex wrenches included and a flat-head screwdriver, this breech will be attached and ready for your accessories. NOTE: Will support mounting of the LPA MIM sight. This kit may be attached to Crosman airgun model numbers 2240, 2250, 2260, 2289 and 1322 ( not the old 1322s).
