Appreciate the reply, I'm pretty sure its a legit rifle. Its been in the back of the safe for a while and I was looking at it the other day and I always wondered about it.
All the sights I have found have that catch broken in the same spot so I guess its pretty common. The little tab on the bottom breaks off and it sticks straight out the side. I'd like to find a LB marked one, but all of the ones I have found are broken the same way. One day I'll run across one.
Thanks again.
