Product Description
10.5" 338 ARC AR-15 Upper Assembly | 1x8 CMV Pistol Length HBAR Parkerized Barrel | 10" MLOK Rail
The 338 ARC isn't just another caliber; it’s a purpose-built solution for the AR-15 platform that rivals the close-range energy of the legendary .308 Winchester. This system thrives with heavy, high-mass projectiles, specifically tuned for subsonic 250gr to 300gr loads to provide unrivaled suppressed terminal performance. If you're building a dedicated short-range brush gun or a quiet tactical rig, a 338 ARC upper assembly offers the massive frontal area and hard-hitting knockdown power required to push the limits of the small-bore gas gun.
Our AR15 Elite AR-15 uppers are American Made and machined by manufacturers of mil-spec AR-15 components. All barrels are individually checked for headspace using Manson go and no-go gauges.

338 pistol upper
Great little upper and mated nicely with my AERO lower. Handled the subsonic rounds that I bought. So far so good, looks great too!

338 Pistol upper
Love my new toy and got a heck of a deal on it. I would advise getting the adjustable gas block. It was so much easier to tune with one. Cycles like it should.

Sub fun
Got this with the intention to shoot mostly subs. Cycled pretty well out of the box even before adjusting the gas block. Opted for the superlative arms and it dialed it in even better. Will make a great hog thumper.
