Bill Geissele started making upgrades for guns when he couldn’t find what he wanted already for sale.

His efforts started small but ultimately grew into a company supplying a lot of SOCOM operators because of the focus on quality.

Breaking the trend of being just an accessory company, in 2019, Geissele announced they were creating their first full rifle.

The Super Duty they released was only sold to law enforcement and designed for patrol use, not SWAT. Not long after, they released a civilian version of the Super Duty.

Who Is It For? Geissele ar 15

There are a couple of walks of life who will truly appreciate the Super Duty. Because it is expensive, you really have to weigh whether this is the right gun for you.

Most people won’t even shoot average AR-15s enough to push their durability into the championship rounds. The Super Duty is built to keep trucking well beyond that, so heavy users would be well advised to shop Geissele.

The gun feels like a refined member of the AR-15 class. It is solid, with good mating between upper and lower and no flex between the upper and rail.

Despite being robust, it is also light, coming in at 6 pounds 14.5 ounces before optics were added. 

The buttstock and grip are two of the biggest factors in terms of ergonomics. Its Enhanced Sopmod from B5 has great shelves for cheek weld and a good pad to grip your shoulder pocket.


The Geissele grip is more angled in the 45-degree fashion, not closer to the 90-degree angles some companies are using. It was comfortable to me and had a good texture.

Its rail is in that Goldilocks size category of not being too big in diameter or too small.

And we can’t forget about its looks. The appearance of the 40mm green is very distinguished, and little touches like the “G” on the bottom of the trigger guard add to the effect.

The Super Duty looks good and runs extremely well. Trying different drills, I engaged multiple targets at different distances, and the rifle proved fast and accurate.

During testing, we ran 500 rounds of 55-grain FMJ Omusha and another 100 rounds of mixed brands through the Super Duty (and two different magazine brands). It fed, fired, and ejected with 100% reliability.

At no point while running the SSA-E X trigger did I find it wanting. This translated well to speed in particular, as the trigger would probably go even faster than my best efforts — until the gun got so hot my hand needed a break.

During accuracy testing, I was able to pull the trigger back to the wall, settle my scope, and then break the shot. This improved the performance.

The model tested had a 16-inch cold hammer forged, chrome-lined, manganese phosphate coated barrel with a 1-7 twist.

Another noteworthy observation was the soft recoil impulse thanks to the Geissele length gas system (between mid-length and rifle length) and super compact gas block.

Part of this soft and reliable function can also be attributed to Geissele’s Super 42 buffer spring combined with their H2 buffer.

Of course, we have to talk about accuracy. I zeroed at 50 yards with the intention of pushing out to 100 for MOA. Unfortunately, I wasn’t able to get to that distance, but at 50 yards, the Super Duty delivered 1-inch groups.

This was accomplished using the Primary Arms SLx 1-10 and placing the rifle in a CTK Precision gun rest. The ammo used was 55-grain FMJ by Omusha.

Notably, a previous Super Duty I had tested shot an average .85-inch groups proned out on asphalt, balanced only on the magazine.

What Sets It Apart? Geissele Super Duty 11.5

There are a number of things that make the Super Duty stand out. One is Geissele Nanoweapon, a durable solid lubricant that has some fascinating properties.

This stuff protects the underlying metal while having a hardness of its own that is similar to synthetic diamonds. Imagine the Terminator T-1000.

Another key point about the Super Duty is the individual parts are a who’s who of AR-15 upgrades. Many people have installed these in their own guns over the years, but in the Super Duty, they come standard.

This is an upper-tier AR-15 and, as such, is one of the most customizable guns on the planet. Between the Picatinny rail and MLOK on the fore-end, you can mount accessories to your heart’s desire.

In this case, we mounted a Primary Arms SLx 1-10 LPVO. This unit provided excellent service and allowed us to handle up close targets, but also really reach out to greater distances.

Although we only tested to 50 yards, we were so zoomed in that we could easily see our hits on target. With this setup, we added a Holosun on an Arisaka Defense 45-degree offset mount.

This allowed me to leave the LPVO dialed out to distance and quickly engage closer targets without dialing magnification.

By simply canting to the side, I picked up that enormous 32 MOA ring and delivered medicine to all deserving targets.

The Geissele Super Duty is a premium rifle that will provide years of accurate service and do so reliably. Keep it relatively clean, and it may shock you with what it is capable of enduring.

I’ve had the distinct pleasure of testing three different models over the last four years, and they have all been stellar.

Many people won’t understand why you might pay this much for an AR-15, but if you’ve ever gotten into a really nice car — like a Cadillac or Mercedes — it doesn’t take too long to see the value of premium materials and performance.

KOOP ECHT GEREGISTREERD RIJBEWIJS ONLINE

In Nederland, BELGIË, Berlijn, Londen, Stockholm, Toronto, Vancouver, New York, Florida en de rest van de wereld wordt het steeds moeilijker om een geldig rijbewijs te behouden of te verkrijgen. Over de hele wereld is er, afhankelijk van het land waarin u zich bevindt, een groot verschil tussen “koop een echt rijbewijs” en “koop een neprijbewijs dat werkt”. Wanneer u een echt rijbewijs koopt, krijgt u een geregistreerd rijbewijs met alle beveiligingsfuncties. Met het echte rijbewijs hoeft u ook niet bang te zijn voor politiecontrole, omdat ze legaal zijn gemaakt tijdens het registratieproces. Aan de andere kant, voor een nep-rijbewijs dat werkt, is het nep-rijbewijs dat werkt fysiek goed en kan het op grote schaal worden gebruikt, met uitzondering van digitale scans. Bovendien, aangezien het valse rijbewijs dat werkt niet is geregistreerd, zult u niet verwachten dat het wordt gebruikt wanneer er databaseverificatie bij betrokken is. Het neprijbewijs dat werkt, kan echter ook voor online doeleinden en voor sollicitaties worden gebruikt.

Granted, there are Honda Accords everywhere that provide reliable service…but they don’t look, perform, or feel the same.

This rifle is worth saving your pennies for.
