Why Choose a Phosphate Cam Pin?

Phosphate has been the trusted Mil-Spec finish for decades because it’s tough, reliable, and excellent at holding lubrication. Unlike chrome or nitride, phosphate creates a matte, non-reflective surface that performs well in field conditions. For shooters who want traditional Mil-Spec durability, a phosphate cam pin remains the go-to choice.

The Value of a Spare Parts Kit

Every AR-15 owner knows the importance of BCG maintenance. Small parts like the firing pin retaining pin and cam pin can wear over time, and having replacements on hand means you’re never out of action. This completion kit is ideal as a spare parts set, giving you confidence that you can quickly swap components and keep shooting.
