MDM 17 – Geissele Automatics Super Modular Rail MK16

Thursday, September 21st, 2017

The Upper Reciever in this photo is equipped with the M-Lok standard, Super Modular Rail MK16 Rail, from Geissele Automatics (but in Desert Dirt Color rather than Black), and Super Charging Handle as well as a Daniel Defense Barrel and Gas Block and finished off with a SureFire WarComp. US Army Special Operations Command, as well as others, are said to be looking at this configuration. Despite being referred to by some as “URG-I” (Upper Receiver Group Improved) these are parts, intended to replace existing components, giving their M4A1s an update. The Super Modular Mk16 is not available commercially.


For those of you familiar with the Geissele Gas Pedal, that’s one on the lower. It’s ambidextrous and offers a 45 Deg throw from Safe to Semi. The real magic is when you depress the spring-loaded Gas Pedal, offering momentary Full Auto performance, as long as it is depressed. Let go, and the weapon reverts to Semi Auto mode. It takes a couple of magazines to overcome muscle memory associated with the full 90 Deg throws of a standard Selector, but it’s a very fast transition from Semi to Full Auto. There’s no more fumbling with the Selector, just push the Gas Pedal and Rock and Roll. This is an upgrade DoD should consider immediately.


VSASS by Geissele Automatics

Wednesday, September 20th, 2017

Yesterday, we showed you the Super Night Owl Suppressor from Geissele Automatics, but that was just the icing on this cake. What Bill Geissele and his team have served up, is a complete family of rifles called the Very longrange Semi Automatic Sniper System and developed internally under codename JG06. The project started as a single weapon for a special requirement, but it quickly morphed into a family of rifles in .260, 6.5 Creedmoor, and 7.62 NATO.

In late May, I saw Bill at the NDIA Armaments Conference where I jokingly asked him when he was going to take all of those parts he’s developed, and put together a full rifle. It didn’t take him long. They began development on July 1st and completed the weapon just eight weeks later. The result is a weapon weighing 12.3 lbs without a magazine or optic, and is just shy of 43″ with the stock collapsed. As you can see, it’s offered in Coyote 498 anodizing.

You’ll look at it and know that it’s a Stoner pattern weapon, but when you look at the breadth of enhancements, it’s obvious Geissele Automatics has been studying the AR family of weapons, in order to improve what are considered standard design features. In particular, they’ve concentrated on reliability, and there are multiple components with Durable Solid Lubricant by Nano-Composite Coating. Like for instance, the Bolt and Gas Rings feature Nanoweapon coating.

The Geissele DNA is also evident throughout this custom design, whether it’s tried and true Geissele parts, or new fabrications specific to this build. For instance, you’ll notice a Maritime Bolt Catch, but it is crafted from billet and has been modified to fit the VSASS. However, the Super Charging Handle is stock.

While we won’t be looking at the internals, here are a few features. The Bolt Carrier features axial stability enhancements and has a raised gas key, for improved wear. Additionally, they strengthened the upper receiver for improved stiffness near the lengthened Barrel Extension and added a hardened steel Cam race. This is important because the Cam Pin is crafted from a Cobalt alloy which would result in increased wear on a standard Upper Receiver.

The M-LOK compatible Super Modular Rail is super stiff and made from 6061-T6 aluminum. It’s got a full length Picatinny rail along the top and is machined within .005″ flatness. There’s some extra Geissele magic in how the rail attaches with the Upper, like the 2.4″ Barrel Nut. Interestingly, the VSASS Upper Receiver is slightly taller than standard models. Conversely, the Lower Receiver incorporates an enlarged Magwell and oversized Trigger Guard. Both are machined from billet 7075-T6 aluminum.


VSASS relies on the two-stage SSA-E trigger, which is around 3.5 lbs. While there’s an aluminum Buffer plate, the QD insert is steel. In addition to caliber choice, the customer may also specify barrel length (18″, 20″ or 22″), although the .260 VSASS pictured here has a 22″ Bartlein Stainless Steel barrel.

Thankfully, the magwell accepts M110 magazines. Another thing on the rifle that isn’t Geissele, is the B5 Systems SOPMOD Stock. It’s joined by the standard issue Pistol Grip. Many companies provide USGI Pistol Grips because they are inexpensive and it’s one of the most often replaced parts, even on military weapons.

In addition to the full VSASS rifle, they’ve also developed a M110 Capability Enhancement Package. Essentially, it’s an Upper Receiver Group which can be fitted to a customer’s existing M110. In addition to the URG, the M110 CEP comes with a .308 version of a Super 42 Buffer and braided wire Buffer Spring kit as well as an SSA-E Trigger.

You may notice that the top front of the rail is cut back on the 7.62 rifle. This is for an adjustable gas block they developed for VSASS. However, they’ve found these are running well without it. Granted, these rifles are tuned for specific ammo, but the Adjustable Gas Block is there for those who require it.

I had the chance to put a couple of magazines through it yesterday and it shot well. I’ve gone to demonstration ranges where weapons jammed, failed to feed, or exhibited other malfunctions, but not with these rifles. There were three different VSASS and all of them ran like tops, with a constant line of those waiting to get their chance. After all, how could you turn down shooting a weapon with laser-like accuracy? The targets were steel at 600m and the range was live the entire time, so we can’t share any target data with you. However, the steel was falling. The .260 was extremely accurate, even in yesterday’s windy conditions.


The Super Night Owl Suppressor is made from Titanium and specific to VSASS. Bill told me he is not getting into the Suppressor business, but rather that this was a requirement for this weapon. It’s a screw on Suppressor and the serialized shroud comes off the core for maintenance.

There’s a final surprise on this build. This is also the first look at the new Vanguard mount for range finders.

It features a separate cap under the range finder mount portion, so you can take off the diving board without losing zero. There are also screws underneath for added stability. In case you are wondering, that’s the Steiner M5Xi 3-15 in Tan.

VSASS is currently only for government clients. Right now, demand is very high for their products and it was developed for a very specific purpose. However, I expect we’ll eventually see a commercial rifle from Geissele Automatics, even if it’s not this one.

It flips to the side to facilitate barrel changes.

SOFIC – Geissele High Speed Selector for M4/M16

Wednesday, May 17th, 2017

The Marine Corps conducted a study which showed that full auto fire is more effective than semi auto fire when engaging moving targets. However, the weapon had to already be set to full auto. Otherwise, the time it took to rotate the selector switch into position would result in a missed target. They asked Geissele Automatics to take a look at the issue and they came up with the High Speed Selector.

You can think of it as a spring loaded selector with a quarter throw. When you depress it, the rifle transitions from semi to full auto and when you let up, it transitions back to semi auto fire. It’s kind of like hitting the nitrous button on a hot rod.

SOFIC – Geissele Automatics Introduces Mk13 Trigger

Tuesday, May 16th, 2017

This new Mk13 trigger was designed by Geissele at the request of NSWC-Crane. It fits the AI chassis and Stiller action only and is specifically intended for use by snipers. The reason I say this is that because it is non-adjustable, its commercial appeal will be limited. Geissele sets this trigger at the factor and in this case it’s 2-stage and 3.5 lbs. The trigger was also specifically designed to pass Crane’s 5′ drop test unto steel plate with the safety off. This is the first time a bolt gun trigger has passed the drop test with the safety off. Finally, it uses Geissele’s proprietary NanoWeapon coating.

Made from 7075 aluminum, they are available in Black or DDC (Desert Dirt Color) type 3 hard coat anodize.

NRAAM 2017 – Geissele Maritime Bolt Catch 

Monday, May 1st, 2017

The Maritime Bolt Catch was designed to make it easier to use with wet hands or with the palm of your hand. What I really like about it is that I’ve seen many Bolt catches with enlarged upper pads, but rarely do they make the lower pad for locking the bolt to the rear, any larger.

Fits any lower reciever designed to fit Mil-Spec bolt catch. Manufactured from heat treated 8620 steel and manganese phosphate coated.
