WMD Guns NiB-X Nickel Boron Cam Pin for AR-15

Item purchase was accomplished in a timely manner and product was of good quality.

Its a cam pin. Kind of hard to mess this up.

This Pin was SUPER TIGHT! Be sure to clean off excess carbon from testing. But because of the coating, the tolerance is even tighter.Gave WMD a call, and the guys were super awesome. They did suggest buying a full assembled group, just in case, because it's been fit check at the factory.

Was just a hair too large to drop into an Adams Arms piston bolt carrier, swapped it into a radical firearms BCG with no issues.

This Cam Pin has very tight tolerances, We ran them in WMD Carriers in 7.62x39 & 6.8 SPC setups and had to replace them with Fail Zero Cam Pins. They would hang up the bolt rotation and cycling when firing, which created short cycling and mis-loads. PA Customer Service is always top notch and professional, always there for the customers.
