Carbine Upper
I am very happy with my carbine upper. The fir and finish are excellent and the BCG is beautiful. I have not finished the lower but look forward to the same quality when complete.

Bought it , they shipped it, I assembled it and it’s the best money I have ever spent. Highly recommend for anyone who is building a rifle. I used a Ruger lower and UTG stock and everything is good to go.

Sloppy Assembly
Gas block was noticeably crooked (20 - 25 degrees off center) and there was an inch long scratch in the barrel that went through the nitride finish down to bare metal. It looks like whoever assembled it tried to slide the gas block on with one retaining screw already threaded through the gas block. Slow down a little people.

Whatever, it took two minutes to fix the gas block and the scratch isn't really visible. Functions fine and shoots as well as can be expected for such an inexpensive upper.

Price dropped $40 a few days after I bought it. Oh well, it is a good deal at both prices.

Great shooter for the money
Highly recommend. Had the chance to run about 500 rounds without any issues. The nickel BCG is a great addition. It was shooting 1-2 MOA of my range bag so your mileage may vary

Shoots great. Would have been better with 15 inch hand guard that you never have in stock or sell separate from your uppers. Really like the BCG. Very easy to keep clean.

Excellent for the price
Mine arrived with a small blem on the receiver, but I'm not picky at these prices. Shoots 2" groups at 100yds with M193 ammo. Nikel boron bcg is excellent.

Lightweight, quality components, cool look!
Headspace was spot-on.. fired about a hundred rounds through mine with no fails. I'm using it as my nightstand rifle now, with a laser, a red-dot sight and a tac light on it. NiB BCG was super easy to clean. I prefer this to the standard AR uppers by a mile.

Nice light weight upper
Love it. The complete build is amazing. I had to replace gas rings after the first 300 rounds but the rifle is accurate and reliable and extremely easy to clean
Full rifle
