Lantac Cp-r360 Cam Pin

The Lantac CP-R360 Enhanced Cam Pin for AR-15/M16 bolt carriers is a precision-engineered upgrade that swaps out a wear-prone stock component with a stronger, longer-lasting alternative. Standard cam pins develop sharp edges where they contact the receiver's cam channel, accelerating wear over thousands of rounds. The CP-R360 changes that geometry with a domed head design that routes load away from stress points, keeping your bolt carrier running smooth for the long haul.

Machined from 17-4 PH stainless steel and hardened to H900 specification (approximately 45 Rockwell C), this cam pin is built tough. The polished head reduces friction and drag, while three strategically placed flats—one at the front for insertion without gas key removal, and two at 90 degrees to minimize channel wear—make it both practical and durable. There are no moving parts to break or fail, and the natural hardened finish (copper/brass color) is purely functional, not cosmetic.

If you run your AR hard—whether you're a competition shooter, hunter, or just someone who values reliability over stock parts—this is the kind of upgrade that pays dividends over time. Drop it in during your next carrier cleaning and forget about it. It's a small change that adds up to real longevity.

Frequently Asked Questions

Will this cam pin work with my AR-15 bolt carrier?

Yes. The CP-R360 is designed to fit standard AR-15 and M16 bolt carriers. It installs the same way as a stock cam pin.

Can I install it without removing the gas key?

Yes. The single flat machined into the front of the head allows insertion without gas key removal, making installation quicker and easier.

Why is this better than a standard cam pin?

Stock cam pins have sharp edges on the upper corners that wear against the receiver's cam channel over time. The CP-R360's domed head curves away from those contact points, dramatically reducing wear. The 17-4 PH stainless steel construction and H900 hardening also outlast standard pins.
