Billet Upper Receiver (AR15)

( 0 Reviews )

Buy It (Rainier Arms)

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.  

True to our path, it is a little different than the rest: our own style, a forward assist but no dust cover.  

This receiver is meant for .223, 5.56, 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 installed.

  • Made from billet 7075-T6 aluminum
  • Mil-Spec Type III hard coat anodize with additional interior lubricity coating
  • Engraved 'SHARPS BROS.' on both sides
  • Weight: 9 oz
