I had a Uberti "Lightning" carbine in .45 Colt I got in a trade. Using dummy rds, I managed to break a part that took three months and many phone calls/emails to replace.
Once repaired, I sold it and the new owner is delighted with it to the point where he had a custom length butt stock made for it!
What I didn't like about the design is that it lacks a bolt lock when in battery and the slightest rearward pressure on the forestock would unlock it and cause a light firing pin strike on the primer.
Gave me the creeps wondering what would happen if a rd ever went off in that condition .....
Advice - sell it to someone you don't like.
