The sling set up works fairly well for me. I tried an HK hook on the sling point on back of receiver but it rolled around and was awkward. I run SOPMOD stocks on my ARs with the sling mounted QD on the opposite side of stock so this is a similar and familiar feel for me, if not ideal.All these new FDE SCAR 17 owners gave me an itch to pick one up also. Nice set up, spermgewehr. How do you like the sling mounted thru the slot in the stock?
