LDC for 13XX with stock barrel
Want to quiet down your Crosman 13XX, but don't want a longer barrel? I developed this LDC to work with the stock barrel length. This LDC comes with a tool steel pivot pin and a new trigger to help you get the most out of your build. The LDC features an integrated front sight, giving you a longer sight radius for better accuracy. By following the contour of the pump tube, this compact LDC packs a lot of volume in a short package, really taking the noise down.
Your 13XX will require some simple modifications to make it work. First, your forearm will have to be cut to match the profile of the inner metal lever (photo 1). Second, you'll want to chase the pivot pin hole on your pump tube with a 3/16" drill bit, then deburr and clean. Next, you'll take your front sight assembly and cut it as shown in photo 2. Alternatively, you can use Crosman part #766-125. Assemble your pump lever with the modified front sight and included tool steel pin. Slip the LDC on until it stops. Tighten the 3 set screws until they stop, do not over tighten.
The LDC will hold your barrel in place, improving accuracy. For even more fun, flip the metal portion of your rear sight upside down giving you a peep sight. Put the Crosman shoulder stock on and you now have the ultimate compact carbine! You can add a touch of paint to your front sight for better visability. The LDC can be lightly sanded and painted for a custom touch.
