I have zero experience with the quick adjust slings. I have narrowed it down to BFG and Boonie Packer 2P-QTA. Will the adjustment hold tight while running long distance? Long distance is 2-3 miles before adjustment. The sling will be sweat soaked as this is a 6-8 mile jog.
The BFG/VCAS may loosen a little (and when I say that I mean like maybe 1.5"). I have no experience with the Boonie Packer slings, but they supposedly make very good slings for the money.
Redi-mag’s 2P-AOTM Combat Sling works quick and stays tight for what I need.
