Ideal building block for a long lasting AR15. This 7075-T6 Aluminum forged Mil Spec receiver with M4 feed ramps has NiB-X coating inside and out to provide an exceptionally tough, ultra-smooth surface finish for outstanding wear resistance and lubricity. A ceramic color topcoat is then applied to the outside of the receiver only. Leaving the inside wear resistant and lubricious. Add an NiB-X charging handle and NiB-X bolt carrier group to compete the upper receiver.
