AR-15/M16 NiB-X® BOLT ASSEMBLY

AR-15/M16 NiB-X® BOLT ASSEMBLY Reviews & Ratings

Nickel Boron exterior gives this bolt an incredibly hard finish that protects against wear and corrosion for the ultimate in durability. The extreme smoothness and built-in lubricity of the coating also reduces friction and gives carbon deposits nowhere to stick, so bolt can be easily wiped clean with a cloth or nylon brush. Comes complete with ejector, extractor, and gas rings installed.


SPECS: Carpenter 158 steel, NiB-X® coating. Ejector, extractor, and gas rings included. Fits .223 5.56mm, 300 AAC Blackout, and similar AR platforms.

Mostly Easy Cleaning
There is no one-step solution to preventing carbon build-up at the throat, and WMDs Nib-X is proving no exception for me. A lite application of Snakeoil WEP synthetic extreme temperature range grease prior to firing greatly reduces sticking; otherwise a mil-spec parkerized bolt seems to work as well as untreated Nib-X. If not treated with WEP, Mothers Chrome polish seems to both dissolve trace residual embedded carbon while restoring near new finish; cant really speak to impact on embedded Teflon molecules at metal surface.
