Product Description

The HK MR762 A4 Upper Receiver Kit is a factory-built upper receiver and barrel assembly designed for the MR762/7.62 NATO platform.

This complete assembly features a 13-inch barrel with 5/8x24 muzzle threads, a free-floating handguard, and an adjustable gas block to better tune the rifle for different conditions and suppressor use.
