Me too if I take the limiter out.
Honestly, I doubt a cop or court will care if you are using ACR mags or not, it is a sham. 5 rounds is 5 rounds and 10 rounds is 10 rounds.
Well... mag is mag.
As of now... mag is mag.
Same reason why ruget pcc is... 10 round mag.
Gotta play their #### #### games. Not my fault they are retarded.
