I had a LK93, it may not have been clean but it was well made and accurate. Im not 100% sure it would be my first choice for a youth gun but it would at least be a tie for first place.
Im actually kind of surprised no one has offered a 45cal youth rifle in years. Something like a Wolf or Impact in 45 would be very popular IMO for anyone that wants less recoil in a smaller package with less of a longer range sacrifice.
