I'm looking for 2 point slings like I can sometimes see on youtube. The ones that carry front or back and transition to fire position and adjust with one hand. They show them, but never seem to explain where to buy them. I've tried a couple that looked good, but don't adjust well and I guess to save production costs, they are so short as to just be usable as single shoulder carry generally with a slide buckle at an annoying pressure point.
