Minor packaging issue on first attempt but the company quickly made it right. Would recommend in the future. 4 stars now for good customer service.

The upper I ordered fit perfectly on my lower. Looks great and shoots great.

Other than my mistake of ordering my 20" 308 upper just a few days before a big labor day sale (shipping out took forever with the flood of orders after mine)- I've got nothing but positive opinions toward Moriarty's products.

It fit up to my lower very well and even with cheap Winchester white box fmjs I was able to get a few groups under an inch @102yds during break in.

With new hornady match brass and 150gr Interloks over my favorite powder- it's capable of sub 3/4 inch groups if I don't get excited and pull a shot... So I'd have to say they're using good barrels and have well trained assemblers slapping these things together.

I was going to get a "tanker" style brake to swap out with the "shark" because i don't really need the tacti-cool points on the end- but I'm not going to mess with the harmonics now that I know it's this accurate...

The wait was well worth it and the prices are very hard to beat with this kind of performance.

I have been very impressed with this upper. Very well made. It cycles many different weights and brands of ammo with no issues. I highly recommend
