We often get asked which upper matches the best with our 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 SBUR03 matches all of our lower receivers perfectly, but it also matches the lines of our hand guards perfectly as well. 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 our lower receivers. Anodized black. Comes with forward assist kit and dust cover installed.
Features:
- Made from billet 7075 T6 aluminum
- Mil-Spec Type III hardcoat anodize
- Sharps Bros’ discretely engraved on both sides
