Well next step anyway . I have wanted a ak100 front sight for a gun for a long time.i cobled together scrap parts and junk! Kusa had ak100 sight for a short time so I got one! I had to reduce the barrel diameter to press this in place. I don't have a lathe so sand paper and a wrist stronger than when i was 14 and about 30 min did the trick! I took .12 off the diameter. Then with barrel .03 bigger than the front sight I used my press to push it on. I still need the 3mm pin holes drilled and reamed . Maybe 2027 I can shoot this!!
