Original Ciener 'Hohrein' 556/Mini-14 .22LR conversion kit with a 30rd mag. I used these years ago when I had a couple KAC-556F's. SOld the guns off years ago and just found the the kits. This is the early better running kit. The original black foam is all broken down, so I cleaned up the inside of the plastic case as best I could and installed new soft foam. Complete kit, manual & 30rd mag. What you see in the pics for $350 + $15.50 shipping. USPO MO. Thanks, Dave
