Recoil Pad "Sharpshooter" With/Sight Pocket, Exclusively For The KT Sub2000 Foldable Carbine "Sharpshooter": Standard Length (LOP 15), With Sight Pocket. This unit will work on all of the Sub2000 firearms and will accept the stock KT front sight and the Red Lion front sight. (Will not work on Sub9/40 firearms.) The exclusive and patented (ATI) Advanced Technologies International recoil pad is an innovative design for the Keltec Sub2000 firearms 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. Kevlar added for added strength. A front sight pocket has been engineered into this recoil pad to protect the front sight while the firearm is in a folded state. Both the factory KT sight and the replacement 'RL' sight can be used with this ATI recoil pad. (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.
