Geissele Super Duty MOD1 5.56 NATO 14.5" 1:7" CHF Chrome Lined Pinned & Welded Bbl Black Complete Upper Receiver Group 08-547B

The Geissele Super Duty MOD1 5.56 NATO 14.5" 1:7" CHF Chrome Lined Pinned & Welded Bbl Black Complete Upper Receiver Group 08-547B ships as a genuinely complete assembly, BCG and charging handle already installed, so a compatible lower is close to the last piece needed to finish the build.

The 14.5" barrel is cold hammer forged with a 1:7 twist and chrome lining, finished in Geissele's own balanced profile for weight and strength that doesn't compromise either. It's pinned and welded to a HUXWRX Flash Hider-QD 556, a detail that matters beyond just suppressor readiness: it's what keeps this Geissele Super Duty 14.5 upper configuration out of NFA territory despite the barrel length.

Cycling runs through Geissele's Reliability Enhanced BCG, Nanoweapon coated with a chrome-lined gas key for corrosion resistance that outlasts a standard finish. A 13.5" MK16 Super Modular Rail mates to this 14.5" Geissele Super Duty build through Geissele's center aligning tab, giving extensive M-LOK real estate without any risk of the rail working loose over time. The Airborne Charging Handle rounds things out, ambidextrous and built for consistent cycling under pressure.

Finished in black and weighing approximately 4 lbs 3 oz, this Geissele 14.5" upper is a genuinely complete, ready-to-run assembly for tactical and competitive builds alike.
