20″ 6mm ARC Medium Rifle M-LOK Upper Assembly
A premium upper assembly engineered for precision without compromise. This means starting with a top tier mil-spec forged upper receiver, using a nitrided steel gas block as opposed to phosphate or aluminum, quality American Made M-LOK handguards and one of the finest nitrided barrels you’ll find anywhere. This also means taking the time to ensure that the upper will function flawlessly with the advanced 6mm ARC cartridge. We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the properly torqued barrel nut and muzzle device.
Bottom line is this: you hear all the time about guys buying a budget upper and it not delivering the precision potential that the 6mm ARC was designed for, or having to send it back because of some hardware defect or other issue caused by a careless assembly process. That is why we use top tier components and assemble each unit to the highest standard of quality. We want your upper to deliver the exceptional long-range performance that makes 6mm ARC special. In fact, we guarantee it will.
Buy with confidence, this upper is backed by our 30 day satisfaction guarantee. Buy it, run it, push it to 800+ yards, and if you aren’t satisfied you can send it back for a full refund.
