My buddy has one of those. Great gun. With this particular purchase the focus is on the frt, and what gun will be the most fun with it. I don't consider the FRT to be anything but a toy for lots of manufacturing and legal reasons. Truth be told, this is my second choice. The ultimate gun for an frt would be a Thompson 45, but I am yet unaware of anyone making that adaptation. It's got a bit of a hard on just thinking it's that gun with an frt and a drum mag 😂🤣. Depends on The gun. On some you have to swap out the spring, but on others like the MCX rattler and a lot of the newer guns, you'll have a valve that can be adjusted at the front of the gun to change the gas pressure. Suppressors are great, but you're missing out if you haven't been using subs.
