AR-10 Complete Upper Receiver

Very nice fit and finish fits my Juggernaut lower perfect. I own Daniel Defense Q and Noveske also and this is just as good if not better thank you and I will buy your 9mm too

Thanks for the great service and very satisfied with the upper. Everything works wonderfully!

Came in, in a timely manor, to include perfect fit to the lower. The entire upper was is pristine condition from assembly. Functioned flawlessly out on the range.

I really like the gun overall, but I had to do some fairly frustrating troubleshooting to get it to cycle correctly. I got the whole kit, and from first assembly, the bolt / carrier were clocked incorrectly or machined poorly and was causing binding in the lugs between the barrel and bolt. I finally worked it back and forth (hard) enough so it could be charged. Afterwards I went to go out and shoot, and found that it consistently was light striking the last round in the mag. So I did my research, disassembled the carrier multiple times and going to more than one gunsmith and finally found the aforementioned issue causing the lugs to round off after a couple mags. At this point I just chucked the entire bolt and carrier and bought an Aero Precision nitrided bolt and carrier and it fixed every problem I had, no light strikes, no binding, nothing.

This is my first AR10 from jugger and I am greatly pleased with robustness and accuracy, it is at same level or above much higher price uppers. I will get another one pretty soon.

This is the crown jewel of my firearm collection. I had originally purchased a LWRCI lower with intentions of purchasing the upper later, well they changed the design and for years I was stuck with a useless lower. I say all this to say don’t purchase any AR weapon that uses mostly proprietary parts or any that has a proprietary upper or lower. I was able to sell my lower to a guy that had a similar problem but with an upper. For the money I received for my lower I was able to purchase most of the parts to complete my juggernaut build. The fit and finish are impeccable. There is a set screw to tighten the fit between the lower and upper but in my opinion it is not needed. And the hand guard is very solid and precise. Come on all accessories mount very well without any issue the fluted barrel is beautiful Andy flash suppressor does a good job of keeping a barrel stable. The charging handle is a high-quality ambidextrous, and looks like it would come from a company like geissele. Lastly, how does the thing shoot, well I am no marksman. (And that’s a true statement. I missed it by two) but with this rifle, I am able to shoot a 1 inch group at 100 yards.

The upper came complete with everything you need minus the sights and optics. It is nice quality and matches up with the lower perfectly. Good job Juggernaut!

Nice upper, very happy with it.

Huge thanks for the guys at JT for helping build the AR10 I’ve always wanted. They guys were beyond professional and patient. The rifle is a solid build and smooth to shoot.

I couldn’t be happier with the options and the quality!
