The Kel-Tec SU/PLR Picatinny Adapter Stock Kit adds a 1913 Picatinny rail section to the rear of any Kel-Tec PLR pistol or SU rifle that has a pistol grip. That rear rail gives you a mounting point for side-folding stocks and braces so you can set up your PLR16 or SU platform the way you want without chasing a proprietary fit. For owners who have wanted to run a folding stock or brace on a PLR pistol or SU rifle this adapter is the piece that makes it possible.
The adapter is machined from aluminum with a black finish so it stays lightweight while holding up to hard use at the range. Kel-Tec includes two mounting plates that lock the adapter to the firearm for a secure and solid fit. Installation is straightforward on any PLR pistol or SU rifle that carries a pistol grip and once it is on the rear of your firearm is ready for whatever 1913-compatible hardware you plan to run.
The adapter is built to the 1913 Picatinny standard so it works with any stock or brace designed for that rail. That gives you a wide field of stocks that fold to the side and braces to choose from instead of locking you into a single option. Keep in mind the stock or brace is not included which lets you match this 1913 Picatinny rail adapter to hardware you already own or intend to buy.
