Geissele Automatics Super Duty Build Kit (Black) with 10.3" MOD1 Complete Upper & Super 42/H2 Buffer System
This Geissele Super Duty build kit centers around a Super Duty stripped lower receiver (Black) paired with a factory Super Duty MOD1 10.3" complete upper receiver group in 5.56mm NATO. The upper features a CHF, chrome-lined 1:7 twist Geissele-profile barrel, 9.3" MK16 rail with Geissele Center Tab interface, Super Compact gas block, and a HUXWRX Flash Hider-QD 556 muzzle device.
Included with this kit is an Ultra Duty lower parts kit in Black (no trigger, grip, or stock) and a Geissele Premium MIL-SPEC buffer tube assembly with Super 42 braided spring and H2 buffer. An OEM Geissele upper box is provided; it is not the original factory-matched box and the box label information is not correct for the upper included.
