Sharps Bros AR-15 UPPER RECIEVER ASSEMBLED BLACK 5.56MM SBUR03

Joined with the company's unique and eye-catching lineup of lowers and handguards, Sharps Bros. developed its SBUR03 Upper Receiver, which is a completely assembled unit designed for use with all standard AR-15 upper-receiver components and calibers.

Each of these Sharps Bros. Assembled Upper Receivers feature an installed forward assist and dust cover. All builders have to do is add the barrel and handguard of their choice, as well as a bolt-carrier group and charging handle. The upper is built from 7075-T6 billet aluminum and features a mil-spec anodized finish.

This Sharps Bros. upper receiver is compatible with standard AR-15 cartridges like the 5.56 NATO, .223 Rem., 300 BLK, 224 Valkyrie or 6.5 Grendel. However, the ejection port is not large enough to accommodate larger calibers like the 450 Bushmaster, 458 SOCOM or 50 Beowulf.
