So after warped op's and lugging my gun for the day its not easy carrying my masada all day I decided to look for a sling adapter as i thought it would be easy..... or I thought after looking for hours and answers for a sling adapter I found out that there are no sling adapters specifically made for the A&K version. Everyone on other forums say they bought this and that and claimed that they don't simply fit. I checked the prices on the adapters and range from 20-25 bucks a pop. After a few years of the masada being out you would think they would have more accessories out..sadly not. So I came across a kid on youtube who made his own simply using a 8/32x2 eye bolt. I went to Home Depot found my bolt and tried it.. it fits and no it is not the most tactical look but once I spray it black it will look like its part of the gun I was able to fit my sling loop through the eyebolt. The only problem I see in the future is that during use the bolt could unscrew itself with all the twisting and turning. So I will get some loc-tite and see if it holds after I field test it the way it is now. I know a lot of us don't have a masada for all I know just FACE and myself have one but if you have held back buying one due to the lack of a sling adapter this should solve your problem.
PS: I saw another person use an MSA with the same size bolt 8/32x2 and it looks awesome but still costs you 20 bucks or so for that.
