AR15 Upper

This AR15 upper receiver is a perfect match for any of the Sharps Bros. lower receivers. It also aligns flawlessly with the lines of their handguards. Designed for .223, 5.56, 300 BLK, and 6.5 Grendel calibers, but note that the port opening isn't large enough for 450 Bushmaster, 458 SOCOM, or 50 Beowulf.

Using this AR15 upper is easy. First, make sure it's compatible with your Sharps Bros. lower receiver and the caliber you're using. Simply attach it to the lower receiver. When handling, always ensure the firearm is unloaded. For maintenance, clean it regularly with appropriate cleaning tools after each use. Keep it in a dry and safe place. Don't try to use it with calibers like 450 Bushmaster, 458 SOCOM, or 50 Beowulf as the port opening is too small and it may cause malfunctions.
