Had a couple questions regarding the MPX foregrip:
1. Is it legal to attach a foregrip to the MPX or do I need get ATF stamp? I plan to SBR it but in the meantime, was curious if I can legally do this.
2. Ordered a foregrip off eBAy that should fit the Picatinny 1913 rail and the foregrip was too narrow to fit the rail of the MPX. Can anyone recommend where to fine one and the make/model #?
Thanks,
TB
