Let's talk about it. Do you have a firearm that is dedicated to your Vehicle?
To me a truck gun is a $300 or less Pistol or shotgun that"s always in the vehicle. Has nothing to do with my EDC. You can build an AR pistol now for about $300 but, not sure I'd leave it in a truck. Trucks are thief magnets looking for guns.
No, it’ll get stolen. Vehicles are almost as secure as tents.
My truck gun is a psa ar pistol 10.5" in 9mm that takes glock mags. My reason for the gun is that I EDC a g19 and also keep mags strategically placed in my truck so why not have something that takes the same mags and ammo as my EDC but can also be more accurate when I need it.
The advantage that should have been noted is that the AK with the unnderfolding stock can be fired but the AR with the folding adapter gets you only one shot if there's a round loaded.
This is kinda one of the advantages to the AK vs the AR in the "truck gun" category... disposability. An AR with a red dot, a lawtac folder, and all that other stuff gets to have a budget that's a bit too rich for my blood to risk getting stolen.
