Extremely well constructed

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 perfect 10

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.

AR10 upper

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!
