M16/AR15 Bolt – 9310 MPI (5.56) – Completion Kit – Black Nitride

$129.99

Our M16 / AR bolt completion kit comes with everything you’ll need to finish your rifle’s AR15, M4 or M16 Carrier. This premium backup bolt is a 9310 MPI spare bolt that perfectly fits the M16 and AR15 carriers and has a black nitride finish that provides increased corrosion resistance, natural lubrication and improved strength. When comparing 9310 vs 158 bolts, 9310 steel bolts provide a more reliable and durable base metal. The Melonite coating combined with 9310 steel is able to withstand more firings than the surface-hardened 158 steel bolts. Black nitride coating provides the smooth look and feel that also delivers the lubricity necessary for reliable functionality.
