Description
This service is a shot peening service for upper and lower receivers, along with any other aluminum or steel components. Shot peening is a process used to strengthen, increase wear resistance, increase corrosion resistance, and provide a uniform pattern to the surface of a component by way of spraying high pressure steel shot against the surface. This is most recognizable in the HK line of MR and HK416/417 line of rifles. It’s the “pebble” pattern in the upper and lower receivers. This service is designed to give your bare aluminum lower or upper receiver the same, matching finish, while also giving you all the legitimate benefits of shot peening. It’s a unique finish that will set your build apart and is the correct, proper pre coating treatment for correct, accurate HK type builds (but is great for ANY AR15 type build). We are the only shop offering this service on small scale, single part basis. This must be done to the bare aluminum, before anodize, CeraKote/Moly Resin finish or any laser engraving. We can also do all these as well, contact us for more info.
