Buy Geissele Duty Rifle, 16″, 5.56 – Black

The Geissele Duty Rifle is a high quality firearm that meets the needs of cost conscious shooters who demand performance and reliability.  Completely assembled in-house at our facility in North Wales, Pennsylvania, the duty line is based on Mil-Spec reliability with Geissele upgrades, and offered at a price that is accessible for Police Departments and the individual officer, as well as anyone looking for a duty grade firearm to depend on.


This duty firearm comes with a Geissele G2S trigger.  The G2S is a non-adjustable two-stage trigger and allows precise and accurate trigger control. The G2S is manufactured from the same tool steel as the SSA and the sears are also wire EDM cut. Visually, from the outside of the weapon there is no difference from the SSA and the feel and is the same.  The G2S’s two-stage design allows the trigger to be light enough for accurate and precise shots, but forgiving enough for up close work.  The Super Duty lower is precision machined from 7075-T6 aluminum and features a Tier-1 Mil-Spec Lower Parts Kit upgraded with a Geissele Maritime Bolt catch and a Geissele Mag Release. A high quality mil-spec Geissele Buffer Tube with a Super-42 Buffer & Spring Combo configuration ensures this firearm is properly tuned out of the box.


The upper features an M4 receiver with a forward assist, dust cover, and M4 feed ramps. The included Geissele Reliability Enhanced Bolt Carrier Group is 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.


Chambered in 5.56mm, the CMV Steel, chrome lined, HP/MPI tested, button rifled, mag phos coated barrel features bomb-proof installation of our Super Compact Gas Block.  The handguard is a version of our MK16 Super Modular Rail currently fielded by USASOC and renowned by operators for their performance and comfort. The MK16 series of rails feature M-LOK technology in the 3, 6 and 9 o’clock positions allowing the end user full customization and modularity to securely mount lights, lasers and other desired accessories.  A Geissele A22 Grip and Magpul CTR Stock finalizes this high-end rifle that offers the user extremely dependable accuracy and performance.

What is Geissele Nanoweapon?

Geissele Nanoweapon (also known as Picatinny DSL) is a family of Durable Solid Lubricant coatings which was developed by ARDEC. It is available exclusively from Geissele Automatics. We continued the development of Picatinny DSL so that its level of corrosion, wear and abrasion resistance is currently unmatched among firearm coatings. Nanoweapon is applied at low temperatures so that the underlying metallurgy of the part is non effected by the application process. Our coating also has a surface hardness roughly equivalent to synthetic diamond. This makes Geissele Nanoweapon harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.
