Some on this site have purchased REP guns, or Remlins as we like to call them and have been satisfied with them. Others, as you have already noticed, have had some serious issues with their guns. Some have been so fed up with them they have returned them for a refund.
Last winter I found a GBL in the used rack at a gun shop I frequent. I was told it was new, but being sold as used. That should have tipped me off right there, but I was blinded by the fact the price was cheaper, it had a big loop and brown laminate wood. It looked beautiful! I bought it. It seemed fine in the store, although it did cycle rough. I assumed that wasn't unusual since most new Marlins cycle kinda rough. When I got it home I started to look closely at the gun, especially the cycling of the lever. On closer inspection I noticed the bolt wouldn't close fully unless I cycled the lever with authority. Again I thought its new and tight, it just needs time. Well, it needed more than time. Theres a machined groove next to the breech end of the barrel & when you close the lever the peice that is connected to the bolt wasn't lining up with that groove unless I slammed it shut. I thought about taking it to a gunsmith and having it fixed, but that would cost me money. Anyway, I took it back to the place I bought it and they refunded my money without a problem.
They happened to have a new JM stamped 1895G in the glass case behind the counter. It cost me a few bucks more but it was well worth it. Buy a JM stamped gun, you'll be glad you did.
