Weapon-Retention Solution For Tactical Environments And Missions

The Magpul MS3 Multi-Mission Sling was designed to give a versatile weapon-retention solution for a multitude of tactical environments and missions. It allows an operator to leverage the maneuverability of one-point attachment for direct action, or two-point attachment for stability.

It features Single-hand adjustments and quick-release, positive-locking hardware that provides flexibility and durability in a truly adaptable sling system. The MS3 enables seamless transitions into an array of shooting positions without getting bound or fouled.

Minimizes Bulk and Effortless Sling Adjustment

The Magpul MS3 Multi-Mission Sling incorporates a new low profile quick-adjust Slider which minimizes bulk and allows for secure, yet effortless, sling adjustment. It allows switching from Weapon Shoulder to Reaction Shoulder for shooting around corners, under vehicles, or to minimize exposure.

The MS3 is a standalone and rapidly-convertible accessory used in conjunction with the Magpul ASAP plate (sold separately). It can also increase the survivability of the operator by keeping the weapon in the fight in case of injury to the operator’s shoulder, arm, or hand.

The Webbing length has also been increased for a comfortable fit with all body types and armor configurations.

Magpul ms3 sling

Great sling

First time using a sling works well

Ok but over priced

Slide adjustment slides loose with every step in the 2 point carry.
Works better in the single point carry. Clips and rings seem solid. A little over priced but it works.

<p>Thanks for sharing your feedback, Matthew. We'll be sure to let the manufacturer know about the issue.

Magpul MS3 sling

There are 2 major faults with this sling.
First is the slider adjustment it works way to easy goes out of adjustment when you don't want it to.
Second is the sling cuts into your shoulder very uncomfertable to wear.
Highly over rated sling. Paid top price for this and can't use, very dissatisfied. Save your money and buy a different sling.

Thanks for sharing your feedback, Mel. We're glad you're satisfied with your purchase. Cheers!

Great sling for the money

This sling is versatile and easy to install that gives you the flexibility to attach it in either a single or double configuration . I was surprised how easy it adjusts to tighten or loosen to meet your need with the slide buckle. As usual, the At3tactical team’s customer service is always top notch.

Thanks for sharing your experience, Glen. We're glad you're satisfied with your purchase. Cheers!
