Most Helpful Positive Review cleanest running AR upper.
I got it for my Rattler to shoot 556, however it comes with everything needed to build another AR IF you have a receiver. So that’s what I’m going to do in the future to add a second piston AR to my collection. If you are planning to build an 11” AR and don’t mind spending on premium parts, this is a good way to go. For those who haven’t shot a piston AR, you’ll thank me after shooting it the first time with some significant amount of rounds & come home to clean it, Voila! The receiver looks like you already spent some time cleaning it.

Sig MCX upper

by Taylor, Verified Owner from MS, United States Written on January 27, 2023
This is a great product from Sig but it is over priced for just a upper receiver with out the adapter, trigger or the folding hinge apdater. The description states it comes with all the adapters and trigger but it doesnt. Buyers beware.

Not As Advertized

by The MC, Verified Owner from VA, United States Written on August 8, 2022
This is an indifferent review. I cannot write a review for this product because the one i received did not have anything but the upper. No trigger or adapters. I caj that the stock virtus trigger is good, but not a G. The 11.5 itself is a good upper runs well, but, but not with low powered 223.
