Frequently Asked Questions

How do you adjust the length of the Magpul MS1 Padded Sling?

The Magpul MS1 Padded Sling features three adjustment zones (front, middle, rear) using polymer fit buckles. You can slide the buckles along the webbing and double the webbing back through the buckle to secure the desired length for optimal fit and retention.

What is the function of the MS1 slider on the sling?

The MS1 slider allows for rapid, one-handed length adjustments. Pushing the slider forward tightens the sling for closer carry or shooting support, while pulling it back loosens the sling for more relaxed, hands-free carry.

Can I attach other hardware to the Magpul MS1 Padded Sling?

Yes, the MS1 Padded Sling is compatible with additional options such as sling loops and QDM swivels. It can also accommodate any compatible one-and-a-quarter inch sling hardware or adapters for customization.

How do I prevent the webbing on the sling from fraying?

If you need to trim excess webbing, it's recommended to bind the cut end by briefly melting it with a flame. This process seals the fibers and prevents the webbing from fraying over time.
