AR-15 grip screws are easy to add to any receiver, but they require a long Allen key that travels the full length of the grip before bottoming out on the Hex screw head inside. In the shop, this is no big deal, but what if you have to do fixes and maintenance on your rifle in the field? The Armaspec Field Adjustable Grip Screw has an extended profile that allows AR owners to remove their grip easily. Each Armaspec Field Adjustable Grip Screw has an easily accessible screw head that can be tightened or loosened with a coin, key, knife, short screwdriver or other flat-bladed object. This means you won’t have to keep a long Allen key on your kit at all times, just in case. Mfg: Armaspec
