The Viper Sling functions in the same way as our MOUT Sling but with a couple of big differences. First, the main portion of the webbing that supports the weight of your weapon across your shoulder is 1.5" wide on the Viper Sling vs. 1.25" on the MOUT sling. This extra width really helps on heavier weapons such as fully equipped M-4's.

The second big difference is the addition of shock cording, housed in tubular webbing, on each end of the sling. This shock cord allows you to sling up a little tighter, yet easily cross shoulder transition. Not to mention the benefits of shock absorption during aggressive movement. 

The third difference is the addition of a second emergency release buckle on the sling loop itself. This gives you the option to disconnect from the weapon and keep the sling on your body, or to disconnect the sling from your body, or both if you're so inclined.

As with the MOUT Sling, the Viper Sling in intended to be used on a weapon with a side receiver sling mount. The body loop secures the sling to a single mounting point. The Viper Sling features a side release buckle assembly that is intended to stay attached to the weapon at all times. The female portion of the side release buckle is permanently attached to the sling itself. With the male portion of the side release buckle attached to the weapon, and the female portion attached to the sling, the sling remains wrapped around the operator's body when the release buckle is disengaged. This is the key feature of this design. If it becomes necessary to unhook the weapon from your body, such as when firing from an unconventional shooting position outside of the capabilities of the sling or something as simple, yet hazardous, as mounting/dismounting a vehicle, there isn't 3 feet of webbing trailing from the weapon. This allows the operator a much greater degree of versatility and safety.

Another important benefit of this design is the ability to wear the sling at all times, without necessarily having the weapon attached. This allows operators to quickly and efficiently lock the weapon onto the sling when deploying on alerts, without having to take any extra time to sling up and adjust. Just grab and go, and lock in when you have the time to do so.

This is also a very useful feature for competitive practical shooters. When coming onto, or off of, the firing line, the weapon can be quickly and safely locked in, or disengaged without any wasted time or effort in adjusting the sling. Additionally, with spare buckle assemblies attached to several different weapons, you're guaranteed to have consistent sling fit with each weapon, since only one sling is involved.

The Viper Sling is constructed from the same 1.5" and 1.25" webbing that we use with our CQB, CST and SOP slings. The Viper Sling is an ambidextrous design. Therefore, no left or right hand versions are required.

NOTE: The Viper Sling works best when mounted to a side receiver sling mount such as on the MP5 A3 series or weapons with aftermarket receiver sling mounts installed. Aftermarket side receiver sling mounts are currently available for most popular tactical long guns that don't already possess this feature. We currently carry G.G.&G. receiver sling mounts for the M-4/CAR-15 on our Sling Accessories page.

An Important Note Regarding Spare Connectors

For many years now, Specter Gear has used a particular 1.25" side release buckle for our sling applications, to include the Viper Sling. Recently, our buckle provider discontinued this buckle. Therefore, we were forced to introduce a different 1.25" side release buckle for use with our slings. The good news is that this new buckle is actually a very nice upgrade. However, this change presents a problem for users of Viper slings purchased before the change. Specifically, those wishing to purchase additional spare connector assemblies.

To address this problem, we've retained a good quantity of the old buckle style so that spare connectors for those older model Gen I Viper slings will remain available. Just order the # 244 spare connector for the webbing attachment type and the # 344 for the ITW MASH hook attachment type.

This situation affects all models purchased before January 2010. If you're uncertain as to which version you have, compare the female portion of the side release buckle to the below images:
