Knoxx SpecOps Folder, Mossberg 500.590.835 and Maverick 88 shotguns. **Not compatible with the 590D double action model. Designed for Law Enforcement, home defense and sporting applications, the patented Knoxx SpecOps Folder shotgun stock cuts perceived felt recoil by over 65%. Based on the highly acclaimed Knoxx SpecOps Stock, this sleek folding pistol grip stock takes the pain out of shooting magnum buckshot and slug loads, even with the stock folded. The sturdy soft-rubber coated folding wire-frame stock with integral rubber butt pad is easily folded over the top of the receiver. This allows for compact storage and increased maneuverability in tight spaces, such as vehicles, motorcycles, hallways and entryways. Extending the stock on the Knoxx SpecOps Folder creates a stable wobble-free platform for accurate slug or shot placement at maximum ranges. A squeeze of the non-slip soft rubber-coated wire frame releases the lock and allows the stock to be folded open or closed. The SpecOps Folder pistol grip contains the unique Knoxx recoil-reducing mechanism. The patented recoil-reducing mechanism reduces muzzle flip in addition to taming recoil. Shooters testing the SpecOps Folder with 3 inch Magnum Buckshot loads have found that there is very little discernible recoil in either open or folded positions, with virtually no muzzle flip. With the stock folded, the shotgun can be held like a pistol, at arm’s length, and fired with no pain or discomfort. Even beginner shooters could consistently hit a 12-inch gong at 25 yards with “00” Buckshot--one-handed! Trying this feat is definitely not recommended with other folding or pistol grip style stocks. Knoxx SpecOps Folder Advantages: • Reduces painful recoil • Decreases muzzle flip for faster second shots • No adjustment or tuning required • Easy installation • Compact design for quick and easy deployment
