Can you install the M64 kit, 1481330, on a stamped receiver? Is the the front trunnion 1 mm or 1.5 mm? Is there a cover latch on the rear trunnion?
Item #1481330 has a 1MM front trunnion and has the tang attachment or cover latch on the rear trunnion. Many internal parts will interchange between the milled and stamped versions of AK's, but the stocks usually do not.
