Cross Armory CRPP308 Pin Pal AR-10 308 Win/7.62x51mm NATO Black Melonite Steel

The Cross Armory CRPP308 Pin Pal is a friction-reducing pin replacement system engineered specifically for AR-10 rifles chambered in 308 Win / 7.62x51mm NATO. It installs in place of a standard AR-10 receiver pin and is designed to reduce binding and metal-on-metal friction at the upper/lower interface, making field stripping and reassembly noticeably smoother.

Each Pin Pal kit includes a precision-machined pin, a matching locking nut, and a custom brass alloy bearing that is the heart of the system - replacing metal-on-metal contact with a low-friction bearing surface. Both the pin and nut are cut from 4140 ordnance steel for extreme strength and durability, then finished in Black Melonite for corrosion resistance and long service life in hard-use conditions.

Sized specifically for the larger, harder-recoiling 308 / 7.62 AR-10 platform rather than scaled-down AR-15 hardware, the Pin Pal drops into any standard AR-10 configuration with no permanent modification. A clean, focused upgrade for AR-10 shooters who want a more durable pin system and easier takedown.
