This high-strength polymer stabilizing fin fits all pistols equipped with a standard AR pistol buffer tube (1.25" 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.
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.
Material: High Strength Glass Reinforced Polymer.
Package: with screw and Allen wrench.
Does not fit adjustable tubes (Mil-Spec/Commercial) or A2 rifle tubes.
