The Geissele Super Duty Build kit features the quality and workmanship you've come to expect from the Geissele name.
The complete upper, chambered in 5.56mm, features a Nanoweapon-coated Surefire Closed-Tine Flash Hider mounted to an in-house durable black oxide coated, Cold Hammer Forged, Chrome Lined, 1-7 twist Geissele barrel. Geissele barrels are precision machined, utilizing the highest quality materials at their state of the art facility in North Wales, PA. The Geissele Length gas system and Geissele Super Compact Gas Block (with bomb-proof installation) ensures reliability and optimal performance in extreme conditions and heavy use.
The included MK16 Super Modular rail mates with the upper receiver via a center aligning tab, removing any chance of rail rotation. This MK16 rail is a variant of the SMR MK16 currently fielded by USASOC and renowned by operators for their performance, comfort, and adaptability.
At the heart of this upper receiver group is the Geissele REBCG (Reliability Enhanced Bolt Carrier Group). This Nanoweapon coated BCG features a properly torqued and staked, chrome lined gas key. The Cam Pin is machined from advanced tool-steel, which is also coated with Nanoweapon for maximum corrosion and wear resistance. The REBCG features extended upper rails, providing greater stability and dramatically increasing feeding reliability. Additionally, the REBCG comes with the Geissele Stressproof Bolt, which is manufactured from Carpenter 158+ steel. Directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has less impurities, the Stressproof bolt is stronger and more fatigue-resistant than you average bolt. The Geissele Stressproof bolt is also forged, not machined from barstock. This optimizes the grain structure of the steel to yield a bolt capable of five times the lifespan of a mil-spec bolt. Each bolt is rigorously inspected, high-pressure tested, mag particle inspected, and Nanoweapon coated.
The Geissele Ultra Duty Lower Parts Kit is made for the most demanding operators and includes all the internal parts necessary to complete or rebuild your lower receiver. This top-tier LPK features proprietary Geissele designs, machined with great care at their facility located in North Wales, PA. Key components are made from Stainless Steel, which offers a much longer life-span and a much lower chance of rusting or failing in extreme conditions or under heavy use. It includes the Maritime Bolt Catch, famous for its aggressive texturing and extended paddles, and the Ambidextrous Super Configurable Safety, which features the ability to easily and securely swap and exchange the safety levers, plus provides the end user a satisfying and positive tactile feedback when the safe or fire position is engaged. The takedown pins and mag release button feature the same “tank treading” as the Maritime Bolt Catch, giving your rifle a tasteful and cohesive look. Included in the Ultra Duty LPK is Geissele’s Ultra Precision Trigger Guard. It is 5-axis machined out of a solid block of billet 7075-T6 aluminum and Type-3 hardcoat anodize to ensure that your build stands apart from any other. Each of these components are constructed with an eye toward improving the usability of the AR platform by allowing for more tactile engagement and easier access to critical control components.
Normally exclusive to Super Duty firearms is the SSA-E X with Lightning Bow® trigger. This nanocoated, two-stage trigger features a wide body and bow shape that finds the perfect balance between a classic M4 trigger and a flat body trigger. The SSA-E X’s light and clean first and second stage pull weights result in a trigger with a smooth, light first stage take-up, and an ultra-crisp second stage break.
The Geissele Premium Mil-Spec Buffer Tube is machined from quality 7075-T6 Aluminum and finished in Type 3 Hardcoat Anodize. This rigid and durable buffer tube conforms to all mil-spec standards and features six pre-set stock positions. This carbine-length, mil-spec diameter Premium Buffer Tube is the perfect fit for your AR-15 lower. Included is a high quality, Mil-Spec castle nut and end plate.
The Geissele Super 42 Buffer Spring and Buffer Combo was designed to improve the function and reliability of the AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the famous German MG42 Machine Gun. This concept acts as a harmonic dampener and energy absorber by allowing the strands to flex separately from each other. This flex helps displace excess energy, which decreases the chance of spring failure and assists with making your AR-15 more reliable.
Compared to the stock spring, the Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (the “twang”) heard and felt by the shooter through the buttstock. The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.
Currently employed by the U.S. military, the B5 stock is a reinforced polymer stock that fits AR-15/M4-type receiver extensions and offers an improved cheek weld, designed for increased comfort and consistency. Two waterproof storage compartments running the length of the stock hold 2 AA or 3 CR-123 batteries. Streamlined contours resist snagging on clothing, equipment, or vegetation to aid in safe and stealthy operation. A Sure-Grip stock latch ensures convenient and intuitive length-of-pull adjustment, while the anti-slip rubber recoil pad secures the weapon to the operator’s shoulder. It features a stainless-steel QD swivel mount and two molded 1¼" wide sling slots.
The Geissele A22 Grip is a modern take on a classic grip angle for the AR15/M4 platform. Incorporating a similar angle as the venerable A2 (including the iconic finger swell), the Geissele A22 Grip also features attractive anti-slip texturing and a thicker palm swell to assist with easily attaining a high-and-tight hold.
