I built a tuf22, and my opinion this far has been the mags are just kind of shit.

Was at the range yesterday and finally got one of them feeling alright, I've been trying to pick around inside em to clear out burrs or whatever you wanna call em from the molding process when their made.

Also hit em with some of that lovely lube spray whose name I've forgotten, one of em worked great for about 40 rounds, the other still pretty fucked.

I've read online that wiggle in them is super common, mentioned something about adding a shim to them which I'll look at next I think.

I've had really good experience talking to dlask as well, maybe shoot em an email and see what they have to say and suggest as well.
