where did you find your stock?
I bought it from AKBuilder
It is not difficult to drill the hole for the latch. I made a jig just for it. I use my dremel and remove some metal where the step is. Yea the barrel will have to be turned down. I am going to push the front sight right next to the gas block, chop the barrel and permanetly attach the 74 brake.
I don't think that's where the muzzle brake goes, if you need help installing it let me know.
Looking good man, glad to see people still building these days.
