Description
Geissele Super Duty MOD1 5.56 NATO 13.9" 1:7" CHF Chrome Lined Pinned & Welded Barrel Black Complete Upper Receiver Group 08-546B is a duty-grade upper built to exceed expectations in both reliability and performance. Featuring a 13.9-inch cold hammer-forged barrel made from mil-spec steel and chrome-lined for maximum durability, this upper comes with a SureFire Closed-Tine Flash Hider that has been pinned and welded to meet the 16" minimum legal length. The 1:7 twist rate allows it to stabilize a wide range of bullet weights, from light varmint rounds to heavy-duty defensive loads.
This upper includes Geissele’s Nanoweapon-coated Reliability Enhanced Bolt Carrier Group, offering exceptional resistance to wear and corrosion. The ambidextrous Airborne Charging Handle provides improved manipulation under stress, while the MK16 Super Modular Rail delivers a slim, rigid platform with extensive M-LOK real estate for accessories. Finished in a Type III hardcoat anodized black, this upper is optimized for professional-grade performance in a highly versatile barrel length.
