rangefinder, etc, won't BE in your vehicle. $150 sks MIGHT, and taken down, 10" barreled CAR-15 MIGHT be in some innocuous little case,or be inside a (velcro sealed) slit in the seat, etc.
The latter can get your guns across Mexico, etc, and into Costar Rica, Belize, etc, and be at least semi-ready for the bandit-punks who you are fairly likely to encounter on such a drive. The taken Down CAR-15, scope, can, .22 unit, etc, can be built into the (home cast) aluminum base for some big pc of machinery that you SHIP to such countries, too.
Try THAT with M1A, bozos.
