AR-15/M16 NICKEL BORON CAM PIN Reviews & Ratings

Precisely machined from high-grade steel alloy to government M16 specs, then given WMD's proprietary NiB-X® nickel boron coating that results in a super-smooth, harder-than-chrome surface. NiB-X® reduces friction to the bare minimum and is impervious to corrosion and abrasion. The slick finish also keeps carbon from adhering, so clean up is much faster and easier than with standard parts. Ideal choice for 3-gun competitor sand other high-volume shooters.

SPECS: Nickel boron finish, silver. Fits mil-spec AR-15/M16 upper receiver.

Does not fit

I figured it was worth the price point to try it out. But like the other reviewer stated, it will not fit into any of my bolts. Measurements show it to be between .001-.0015 inch diameter to large. It will not fully seat and it will not rotate in the bolt. On the bright side I have hours of dremel polishing into it and seems to be making progress and it is now too slick to hold. Maybe one day it will fit, but save yourself the aggravation and pass on it.

TO BIG TO FIT

I bought this for a upper build & liked the idea of the coating to reduce friction. But if you read the description carefully (I didn't) it is manufactured to Gov. M16 specs & then coated. Therefore the coating thickness added to the diameter & it was so tight (yes I oiled it) that it would not seat deep enough into the bolt to allow the firing pin to fully slide through the bolt to engage the primer. Brownells gun tech was very helpful & will replace it with a non coated DPMS cam.
