Look good although the solder joint look like they could of been better (although I know this is a test model).
I hope this doesn't turn into the tsi armory stuff (remember how good it was suppose to be).
Bought mines recently so I can't comment much but its a really nice build, only thing I can comment is the rear iron sight.
You can't put the sight back down when you use the larger ring as it gets in the way (magpul BUIS don't have this problem).
Is your Stock Hinge Connection Plate for WE SCAR Gas Blowback Rifle(I dunno what they call it) of the mainbody breaking apart?
I hear its a common problem :\ ?

If your really dead set on getting duo-optics then get the real steel one. It won't fit without modding it but its the only way your going to get something greater then a one inch eye relief.
I was planning on owning after reading quite a extensive review about this gun and how it can take real part. I just never dab with RS part and its good to know that I can buy them "just in case." TBH I didn't even know the rules for RS firearms besides that I need to get a permit and go through interview etc etc etc
