AR-15 16" 7.62x39 Barrett Style Upper | 15" Lightweight Mlok

I bought this upper for my 7.62x39 build and it works great. The lines match perfectly on my PSA AR-15 lower. I did have some issues the first time I took it out, but that was more in part due to the feed ramps on the mags. I thought I was going to adjust the gas block, but after twenty to thirty rounds everything worked great.

I received my upper and was supper happy with the look and feel. When I finished my build it seemed to not be striking the primer of my bullets... so at that point I contacted Moriarty and they gave me a few tips to try which none worked, then I contacted them again and they asked me to send it in. After a couple weeks I got my upper back and it works perfectly!!! Customer service is absolutely the best!!!! The gun shoots great, 0 FTF and nice and accurate! I have multiple uppers from these folks and am very happy with all of them!

Owned this upper for around a year now. I was interested in putting together a 7.62x39 upper to spread my caliber options in the AR platform, and train cheaper. 7.62x39 is more of a "thumper" cartridge, when considering follow-up shots...which brought me to my interest in the unique muzzle brake for such a caliber. Generally found on the 50BMG, it seemed odd at first. However, it adds forward weight that helps mitigate the barrel rise and recoil. ACCURACY is spot on. I ran 2-shot drills against 8 and 10 inch steel targets, 50-75 yards away, using a red dot just fine - stress FREE, mind you. AMMO USED: Tula, Wolf, Wolf Poly, Red Army, and Barnaul. MAGS USED: CProducts 30rd, and a steel "multi cal" mag(forgot name) @25rds. LOWER RECEIVER: Anderson. TRIGGER ASSEMBLY: Hiperfire EDT DM. Enhanced firing pin. N.B. BCG. ALL worked in harmony with this upper! First purchase with Moriarti Armaments. I would do business with them again.

I received the package.

Thank you again for the outstanding customer service and support.

I have recommended you to a couple other Marine friends who are looking to make purchases this year.

Thank you again and look forward to giving more of my business in the future.

I bought this upper for my ar15 build. Took it out shooting had one problem but it was from the mag not this upper. Great buy and looks good works great with the right magazines. This company is easy to work with had no problems paid and shipped 2 days later got here with no problems.
