This Picatinny to Picatinny clamp can be used to connect our UBL-37 to any weapon with a Mil-Spec Picatinny rail. To maximize the security of the connection, you should choose the longest clamp that your rail will accommodate. To do this, count the number of recesses on your rail. If there are 15 or more, use the 6” clamp to maximize metal to metal contact. If there are at least 10, you can use the 4” clamp. For very short rails, use the 2” clamp. The clamp is made from mild steel and Parkerized for a matte finish. It is designed to allow two 1911 Picatinny rails to make contact and then, by tightening the cap screws, increase the force of that contact to virtually eliminate any chance of shifting.Three cap bolts (6” model, two cap bolts for the 4” and 2” models) extend through the openings between the rails to further prevent any movement of the launcher relative to your weapon. Includes Allen wrench.
