Misc MRX mag question
Hypothetically if a person were to modify a pump action rifle receiver that uses an AR magwell to fit MRX mags would that be legal? If so would modifying the magazine to have only one set of fins and modifying the rifles’ magwell to fit the one set of fins be legal?

Hunting gear guy had a video with his 180 where he was shooting an MRX magazine. It was just never explicitly mentioned and editing was cut such that it never fired 20 rounds. People just don't talk about it because
1) It's not necessarily fast to do
3) It involves cutting up a gun which usually cost people a lot of money (semi-autos these days) and some people aren't keen on that.
And you're also correct; "manual action" magazines that would hold more than 10 and theoretically could work in modern semi-autos didn't exist even 10 years ago. It's one thing to cut up a rifle, but with feed geometry and retention method, there really weren't any options.
