Griffin Armament A3 Grip. An improved grip for the Ar15 series rifle. Their engineering department did a study of available grips, took desirable characteristics of the A1 grip, changed the angle for optimal pointing characteristics, made several variations during product improvement, and the A3 grip was the resulting product. The A3 provides excellent comfort and ergonomic feel, without loss of positive weapon retention or ease of safety selector manipulation. The Griffin A3 is compatible with the USGI trigger guard's winter guard function for gloved or mitten use. Textured to match the Griffin Armament Rail-Shield M-Lok furniture kit, available in four colors- the Griffin A3 grip is an impressive grip at a reasonable price.
