Those slings look sweet a little on the pricey side though. After looking at the Tactical link web site, I didn't see a mounting system for the Benelli M4. Did you have to do some modification to you stock to mount the sling?
I was thinking about using a mount system along the line of the GG&G or the KZ two loop sling adapter. But i have read that those only work on the M1 & M3, not the M4. Or have i been miss informed?
