This is an extended bolt release lever allowing right handed shooters to release the bolt catch without having to reach over the top of the AR-15 to close the action. This design is a very simple "piggy-back" of a rugged light-weight Delrin lever that uses a longer bolt catch roll pin (included) as a pivot axle. The lever only contacts the top of the bolt catch, floats on the new roll pin and extends down towards the front of the trigger guard. The lever requires a definite motion to release the bolt (for safety purposes). Extended bolt release levers ARE allowed for Service Rifle Competitions, and great for Match rifles/Spaceguns. Especially if you have a side cocking upper!! Rapid fire strings are easier! Installation consists of driving out the existing bolt catch roll pin (to the rear) and, leaving the punch in place, driving the new roll pin with lever attached forward, stopping when pin just protrudes from the forward edge of attachment point. The pin is flared at the engraving end to retain the lever. Scotch Tape retains the pin in proper orientation for shipping and is to be removed only after installation.
*May not work with a milled receiver where the width of the receiver is wider than mil-spec.
