$4 roll of grip tape gets rid of my only complaint - DoubleStar Push Button Folding Stock Mechanism w/o Boss

I attached this to a DoubleStar receiver block along with a triangle stock on an AK. I also later gave it a spin with a pig nose adapter I bought that I slapped an AR buffer tube and stock to. Both applications worked pretty well. One other really cool aspect with these ACE hinges is that it looks like they will clear any optics you may be running on your gun when you use their triangle stock, however I've yet to be able to test this as I currently don't own any. My only complaint with this is that there is a little bit of play to it when it's open, however that can easily be removed by applying some rubber or industrial grip tape inside the mechanism.
