For an inexpensive sling that (15.00 w/o swivels) that works GREAT - try a Master blaster from texashuntco.com.

Typical cordura type material, padded section that sits on shoulder with thumb loop. Made in USA, nice construction details like strap ends fused so they don't unravel.

What sets this one apart is the 1' portion going to the rear swivel has a stretch section.

I set the length once and the stretch part does not restrict movement with clothing change. Arm/elbow movement is all that is needed to tighten mount or adjust.

I bought 3 - comes in 4 colors - I used Coyote for the black plastic stocks and Walnut Brown for the wood one. 2 rifles have swivels so I got 2 slings without and one with swivels (these cost more) which is made by Talon. Great sling!
