    Great Value

    Great starting point to build an "M4-gery". Fit and finish is way above average out of the box, with a light but strong free-float forearm, stout "gunner' barrel profile that carries a bit heavy and a bit long compared to a standard M4 but maybe it's just me. Still not a deal-breaker Barrel extension finish is very well done, and the whole assembly fit flawlessly on a 4 separate lowers. The only change I made was to replace the Mil-spec flash hider with a Kaw Valley Compensator I had in my parts stash. Accuracy is 1 MOA with 62 gr Green-tip PMC, and Wolf 62 gr. Well done and value packed upper assembly!!.

    16" 5.56 NATO AR15 Upper Assembly Chrome Moly 1x7

    AWESOME

    Most companies estimate 15-21 days to ship upper receiver and these guys did it in about 3 days. The 16” is perfect length. Shoots very nice without any issue. Would highly recommend if you’re looking for a good priced upper receiver

    Best of the Best

    I have turned 5 friends on to these uppers for several reasons. They have a fantastic hand guard; slim line, Picatinny rails in just the right spots, comes in .223 Wylde, love the matte black finish of the barrels and they do this all for a very fair price.

    Cheap but dont underestimate

    200 bucks and it's a shooter. 100ish yards, cheap ammo, 1x red dot and stayed where I was shooting. Hard to tell from the pic. Bought it for shtf but that chamber is a sweet cut Wylde and never missed a beat. In case you have to switch from Lysol to 223/5.56 I'd highly recommend it. P.s. I never received an email confirmation, however, I did the account stuff and followed that. Impressed with swift delivery amidst this covid19 wait a few weeks stuff. Even more impressed for the price, the upper rail and hand guard line up perfect (pet pieve) and accuracy, cycled flawless, and is light and performed

    Exactly as described

    This upper exceeded my expectations in every way. They shipped it fast. The materials are high quality. The couple questions I had were answered quickly. Going out soon to try it and will report the news of there is anything wrong.
