Cross Armory CRPP Pin Pal Mil-Spec 223 Rem/5.56x45mm NATO AR15,M4 4140 Steel

Cross Armory's Pin Pal provides a more durable pin system to prevent undue wear on the forward pivot point of your AR. The bearing can be press fit without special tools, and won't permanently alter your weapon. It is easily removable should you choose to return to your factory configuration. The Pin Pal system includes a front takedown pin replacement with a locking nut machined from 4140 Ordnance Steel for extreme durability, and a lubricated captive bearing. It has a black melonite hard coat finish.
The Pin Pal model utilizes a Mil-Spec captive bearing made from porous metal with an increased iron content for increased strength and resistance to shock loads. It fits any standard AR-15 configuration, and installs easily on virtually all AR-15/M4 weapons.
