I made this for my Corner-Shot 3.0 https://www.thingiverse.com/thing:3135768 This allows it to be attached to any pistol without a carbine conversion, its a very simple and rugged design. Requires only 2 X M3 bolts and nuts * No supports or raft required. !Don't forget to check out my other Cool designs and Follow my Daily dose of KooKoo uploads, Enjoy ;)
