Not to jack ur thread. But I have the same upper, and I was wondering what kind of front flip sights would i need??? I know Midwest Industries makes two different kinds. The FFG and FFR
I'm not 100%, but from what I hear they have sights made strictly for railed gas blocks. I was gonna use a reddot on this one, but got a good deal on a "modified" upper. Someone in "the know" will surely chime in.
well they make some that fit the railed gas block that are on a even plane and they make them for those gas blocks that sit alittle lower. So i don't know which one to get.
Ak is the front gas block lower than the upper rail? You may need the tall one for the front and the short for the back. I would have to put the sights on to see if they line up. I gave both in stock if interested?
