Geissele's Super Duty upper receiver groups features the latest in weapons technology. This complete 11.5" upper receiver includes a 11.5" mag phosphated, CHF, Chrome-lined barrel with a 1:7" twist and includes a Surefire closed-tine Warcomp. These barrels are precision machined and cold hammer forged in-house at Geissele's North Wales, PA facility. The 11.5" model uses a carbine-length gas system and utilizes a Super Compact Gas Block with bomb-proof installation for reliability and optimal performance.
The Super Duty uses a 10.5" MK16 Modular Rail with M-LOK compatibility and features an alignment tab that mates to the upper receiver. This rail is a variant of the same rail used by USASOC and renowned operators.
Also included is a Geissele REBCG with a Nanoweapon coated BCG for exceptional wear and corrosion resistance. The carrier is constructed from 8620 steel and uses a staked, chrome-lined gas key. The bolt is made from Carpenter 158+ which is forged for a stronger and fatigue resistant structure. Each bolt is inspected, high pressure tested and mag particle inspected.
This is a complete upper receiver and will mount to AR15/M4 lower receivers. All NFA Rules apply.
