Ordered this upper not being able to find any other 12.5 308 uppers, this upper is accurate out the box, has a good heavy feel and easy to dial in with the right optics. Shipping was quick and it came with no issues. When at the range hitting metal targets, it has a ominous "dang, not ding" sound. I love it.

Great, nail driving upper!!
Had a few minor issues taking delivery, however their excellent customer service was very responsive. Minor ding on the dovetail upon delivery, but completely forgotten when I got a chance to shoot it. Weight is perfect and staying on target with .308 recoil is, IMO, alot easier than other AR10's. It felt like I had to intentionally "try" to miss, point and shoot well beyond 100 meters. Built like a tank, quick and dead on accurate. Great Job Moriarti Team!

I ordered this upper and then after a few days, read some negative reviews about these. I just wanted to comment on my personal experience with my order and the 12.5 inch .308 upper I received. Mine shipped in exactly six weeks from the order and got to me in 4 days. I have to say, as a builder of over 20 AR platform rifles and pistols over the last 7 years, this upper is nice, especially for the price. Build was as I requested. Fit and finish were good. Added my BCG and charging handle with no issues. Worked the charging handle a bit, added an empty mag and repeated, bolt held open as expected. Headspace checked good. Ran a mag full of dummy rounds with no issues feeding or on ejection. Have not fired rounds since I just got it tonight but I expect to remedy that this weekend if the weather cooperates.

Best AR Pistol for the price
You most likely can't find a build of this quality at such a good price.
