Designed to complement our featureless grip and provide you with the utmost comfort. Prevents the sharp edges and pinching that the standard mil-spec end plate gives you while using our featureless grip. Machined from billet T6-6061 aluminum and hard anodized. Follows the same shape as our featureless grip to give you the most comfortable featureless rifle out there. Works on any mil-spec AR-15-type receiver.
