Jack Rifle designed by Sharps Bros for Spikes Tactical. This rifle features all three Blackstone coatings. Blackstone DFL on the internals for anti-friction and no lube. The hot points received Blackstone Plus, such as the barrel and gas system. The exterior components were coated with Blackstone HD for added durability, as in the upper, lower, and handguard. Blackstone is a revolutionary coating that has met both MIL-SPEC and ASTM compliance, for its outstanding characteristics and use of Graphene.
