I don't see the value in the interchangeable magwell for the end user, especially when the magwells cost as much as a stripped lower. I could see the novelty having some use in departments where officers are allowed to carry from a list of sidearms, the carbine could be configured to match their sidearm. The fact that a $1600 rifle has what appears to be a mil-spec trigger, at this price point, is unacceptable. Also, for competition shooters being the target buyer, there's no muzzle brake.
I love Nordic. I have a couple of their .223 barrels. All my shotguns sport their parts. I get that something had to be offered that set their product apart from the herd, I just don't think the novelty that is the interchangeable magwell is worth the scratch. I'd rather the money spent on R&D of the magwell had been spent on a decent trigger and brake, ala JP, instead of a function that won't be used by most end users.
