will m4 upgrades get seized across the U.S border?
I have been thinking of spending $500 on upgrades for my m4. i am almost stripping it right down and adding new replacment parts. Im just wondering if these will get seized along the border.
parts im getting are:
metal body for M4
new butt stock for m4
free float rail interface system
Matrix Lipoly Ready 8mm Complete Gearebox for M4
supports grip handle (shouldnt be a problem)
and scope rings.
i would appreciate any help
