I modified my Hawk Industries Chinese 870 a little bit, I have been looking for a single point sling adapter that would fit for quite a while, after not really finding anything I just decided to modify the synthetic stock to accept the Magpul SGA adapter. I spent $125 on this shotgun several years ago so I figured what the heck. I had some trouble with the synthetic stock wanting to chip so the fit & finish isn't perfect, but it's strong and effective.
I guess I forgot to take a picture of the whole thing, it's got a 18.5" cylinder bore barrel with a 3" chamber, and rifle sights
