Used Geissele Super Duty 556 Nato 14.5" Barrel MLok Handguard

Super Duty Rifle, 14.5", 5.56mm - Luna Black

The Super Duty Rifle features the latest in weapon technology available exclusively from Geissele Automatics. This 14.5” rifle chambered in 5.56mm features a Geissele Sparkout Flash Hider mounted to an in-house 14.5” Manganese Phosphate coated, Cold Hammer Forge, Chrome Lined, 1-7 twist Geissele barrel. Our barrels are precision machined and cold hammer forged utilizing the highest quality materials at our state of the art facility in North Wales, PA. The Mid-length gas system and Geissele Super Compact Gas Block (with bomb-proof installation) ensures reliability and optimal performance in extreme conditions and heavy use.

 At the heart of this rifle is the Geissele Reliability Enhanced Bolt Carrier Group. This Nanoweapon coated BCG features a properly torqued and staked, Chrome Lined, Nano coated gas key. The Cam Pin is machined from advanced, tool steel known as H13 which is also coated with Nanoweapon for maximum corrosion and wear resistance. The Reliability Enhanced Bolt Carrier Group also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.

The Reliability Enhanced Bolt Carrier Group comes with the Geissele Stressproof Bolt. Made from Carpenter 158+, directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has less impurities. This makes our Stressproof bolt stronger and more fatigue resistant. The Geissele Stressproof bolt is also forged, not machined from barstock. This allows us to optimize the grain structure of the steel to yield a bolt capable of 5 times the life of a mil-spec bolt. Each bolt is rigorously inspected, high pressure tested, mag particle inspected and Nanoweapon coated.

The Geissele Quick Disconnect (QD) Sling Mount Endplate allows for fast interfacing of slings quipped with QD pushbutton mounts to the lower receiver.  This rugged and reliable attachment point is machined from Stainless Steel that is finished in Black Nitride and staked per MIL STD. 

Rounding up the package is a 13.5” MK16 Super Modular Rail, that mates to the Super Duty Upper Receiver via a center aligning tab that removes any chance of rail rotation. The MK16 family of rails are fielded by USASOC and renowned by operators for their performance and comfort.
