Product Info for Presma AR Pistol Stabilizing Fin

This Stabilizing Fin incorporates a flexible stabilizing area which rests against the inside of the forearm when in the firing position. If desired, a standard sling may be wrapped around the Fin and forearm, further stabilizing the pistol to the forearm in both horizontal and vertical planes. This high-strength polymer product fits all pistols equipped with a standard AR pistol buffer tube (1.25in in diameter), for a secure, worry-free fit. The Stabilizing Fin is a lightweight, clamp-on, ergonomic, AR pistol enhancement and acts as a forearm buttress.image
