Geissele Super Duty rifle, 16" in Luna Black, 5.56mm AR-15

factory rifle with an amazing jet black finish

Geissele's flagship rifle, the Super Duty in 16" with the exciting new HUXWRX closed tined flash hider is a both a fine weapon, and finely crafted.  We all love the DDC / tan colors, but the quality of this finish in jet black is hard to beat.  Geissele has been working to perfect its initial rifle offering, and the Super Duty Luna Black with the cold hammer forged barrel is a crowd pleaser.  Featuring standard mil-spec 1:7 twist 5.56 NATO chambering, a lot of thought and engineering has gone into this rifle and the Geissele barrel, and it shows.

This is current production factory Geissele with the HUXWRX flash hider for 2024.

The Geissele CHF barrel makes is debut in the Super Duty rifle series, and is nice in that it is so normal.  So military.  CHF or button broached are both good.  Geissele is making CHF, and in 1:7 twist with a mid-length gas system and Geissele's low profile gas block, both with set pins and drilled and pinned.  Geissele calls this bomb-proof.  It is a bit of over-engineering, but why not.  When your name is on the gas block, call it whatever you want.  It is a fine gas block, and proven for years.

Interesting as well is Geissele's choice of the HUXWRX closed-tine flash hider.  Geissele's first generation of Super Duty had the tried and true 3-prong SOCOM flash hider from Surefire, then the 2nd generation migrated to a Geissele propriety flash hider.  The use of the HUXWRX gives the rifle a little edge in uniqueness, as well as a nod to the next generation of gas flow suppressors from HUXWRX.  

The trigger is unique.  Geissele has inserted a great Geissele trigger.  Borrowing from the fully automatic, SSF, Geissele offers the SSF -X in semi-automatic, with flat bow and a DLC like coating, along with the BCG, that Geissele calls "Nanocoating."  A fancy name for a diamond like coating that serves to lubricate and resist corrosion.  Geissele has invested quite a bit of time in bringing their Nanocoating to market, and like all things Geissele, there is great quality and a little bit of marketing going on here.  

At the heart of this rifle is the Geissele REBCG (Reliability Enhanced Bolt Carrier Group). This Nanoweapon coated BCG is machined from mil-spec 8620 steel, with a properly torqued and staked, chrome lined gas key. The Cam Pin is machined from advanced, medical steel known as H13 which is also coated with Nanoweapon for maximum corrosion and wear resistance. The REBCG also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.

The REBCG 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 Super Duty lower is precision machined from 7075-T6 aluminum and features Geissele’s Ultra Duty Lower Parts Kit featuring our Ambidextrous Super Configurable safety and Ultra Precision trigger guard. A high quality mil-spec Geissele Buffer Tube with a Super-42 in H2 buffer ensures this rifle is properly tuned out of the box.

Rounding up the package is a 15” 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. An Airborne Charging Handle, ensure smooth and reliable operation.

A Geissele Rifle Grip and a B5 Systems Enhanced SOPMOD Stock finalizes this high-end rifle that offers the user unmatched accuracy and performance.
