Edward, Emperor Arms actually make very decent shotguns including this Single Shot. It is the same quality as the RIA and ATI but is just not as well known. This will be a great Truck Gun in any event. Cheers and stay safe! Emperor and Midland are clones of each other : youtube.com/watch?v=L15zECD2Mmc

I've actually seen people complain about the magazine fed version on the buds community not so much on fit, finish, or function but that finding compatible accessories can be difficult.
We see questions on here all the time about does this fit the emperor arms? And someone will answer yes, and then later the customer check ls back in and says it didn't work.
This shouldn't be an issue with a break open single shot though, not really a whole lot of accessories to put on one of those. But if you were wanting to upgrade or trick it out in anyway might be better off going with a company with more aftermarket support. For just a barebones truck gun it'll work fine.
