Details:

The Valkyrie Bolt Upgrade is offered to meet and exceed all Mil Spec standards by including three of the most significant reliability upgrades you can buy.  This is upgraded to be used for direct impingement (aka gas tube) systems as a replacement/spare.   First, the Bolt is Ion Bonded for superior corrosion resistance and durability even when using inexpensive corrosive surplus ammunition. Second, a Milspec Viton O-ring is installed to assist in eliminating extraction problems in the M16, M4, and AR15.

Adams Arms Advantage:

Our bolts are finished with our proprietary QPQ Melonite process inside and out. Unlike hard chrome and magnesium phosphate, Melonite is a molecular bonding process with the metal. It allows the chemicals to seep down below the surface area of the metal, instead of just adding a top layer. This means that the bolt can offer complete corrosion resistance and virtually no wear. It also means that the protection offered is not just a thin layer on top of the material but actually penetrates layers deep ensuring that it does not wear off.

  • Heat Treated
  • Melonite Ion Bonded

  • Chrome Silicone for Longer Life
