Sharps Bros often gets asked which upper matches the best with their receivers. Any mil-spec upper will work, that is the beauty of the platform... but which one fits and matches the best? The answer is this one.
The SBUR04 matches all of their lower receivers perfectly and has a mil-spec front end thatis compatible with any AR15 barrel nut & any AR15 handguard out there, including those with rear facing tabs.
This receiver is meant for .223, 5.56, .224 Valkyrie, 300 BLK and 6.5 Grendel calibers. Port opening is not large enough for 450 Bushmaster, 458 SOCOM or 50 Beowulf.
Made from 7075-T6 just like their lower receivers, Anodized black and comes with forward assist kit & dust cover installed.
Review by Thang N. on 16 Apr 2023review stating Pairs well with Radian ADAC lower
Fits fairly snug to Radian ADAC lower. The unique look made it stand out to most standard traditional designs. It has all the cool cuts and edges that gives it more of a modern look especially the ejector bump. It also pairs well with the design of the ADAC. Only wish it came in other colors like FDE.

I am extremely happy with how my new AR Pistol looks with “The Jack” at its core. Top quality and great talking point with everyone that sees my new toy.
