Re: SCAR 16/17 slings?
The only good mounting option for the factory front sling point on that system is a 5.56 to the mouth of the enginerd department. I guess it's our own fault for letting all the mods & resources be wasted on redesigning the same feature back & forth half a dozen times. Reap what we sew & all.
Other than that, yes, if you're married to the idea of using the factory front sling point a mash hook or HK hook are about your only viable options.
I don't think the MS2 would be long enough for anyone but the shortest of the Gary Coleman troops even if the jaws would fit.
I'm thinking $23 & the lowpro RSA fixes a handful of engineering faults with that system.
