First post, so sorry if it’s in the wrong forum. I recently picked up a BCM upper that had the A.R.M.S. #50M Bi-Level rail on it for a good deal. I know they’re outdated, but thought it would be cool to make it a little project video game clone. To complete the goal, I would need to acquire the A.R.M.S. #50 Top Rail. Their website is sold out and I don’t think they will make anymore, considering the rail is discontinued. Does anyone know where I could find one? Even by chance if it’s at one of your local shops. I’ve only seen a few places online that have them listed, but each one has a lot of negative reviews and “buyer beware” warnings. I’m thinking my best bet is to wait and see if one pops up on gunbroker or eBay. Any information would be helpful, thanks. I’ve attached pictures of the item.
