magpul two point sling - quick adjust (black) (original version) magpul the ms1 sling is the most versatile addition to the magpul line of rifle slings. this sling system starts as an optimized, dedicated two-point sling. built around our ms1 slider, this system provides rapid adjustments to either lengthen or shorten the sling with no slipping once set, and no tails, loops, or other potential snag hazards. in a two-point role, the ms1 allows easy shoulder transitions, rapid adjustability for hands free rifle carry and shooting support from various positions. the ms1 system also has a series of adapters that are sold separately and based on the ms3 and ms4 slings. in testing, the sling had to survive tens of thousands of cycles in wet, dry and sandy conditions, static load testing without slippage for 72 hours and weighted six foot dynamic drop tests. in addition to the controlled lab tests, we also swam it, jumped it, hunted with it, hiked into the mountains with it, and most importantly shot with it in a variety of rugged field conditions. the ms1 sling is made entirely in the usa, and is fully berry amendment compliant.
