Custom Recoil Pad "Gen 2" With/sight Pocket, Exclusively for the KT Sub2000 (Generation 2) Foldable Carbine. Custom Recoil Pads! The (Gen 2) Recoil Pad is newly redesigned to be used with the newest KT Sub2000 carbine (Generation 2). The exclusive and patented (ATI) Advanced Technologies International recoil pad is an innovative design for the Keltec Sub2000 (Gen 2) firearm chambered in 9mm and 40 caliber. (ATI) design of the recoil pad consists of a soft yet scratch resistant recoil-absorbing silicone. This inert (non-toxic) silicone material distributes the recoil effect over the entire pad surface, reducing the felt recoil to the shooter. The silicone is not affected by time or temperature. A front sight pocket has been engineered into this recoil pad to protect the front sight while the firearm is in a folded state. (ATI) design of the recoil pad features a patented retaining system that permits an easy/fast removal and installation of the recoil pad without the need for any hand tools. The Generation 2 Recoil Pad adds approximately .75 to the overall length of the firearm and provides a counter weight to help balance the heavier front barrel and accessories.
