CMMG Banshee MK4
Best compact personal defense firearm for mobile security and storage.
This is the ultimate compact solution for those who prioritize portability without sacrificing the versatility of the standard AR platform. By shrinking the barrel to its absolute minimum, you gain an incredibly maneuverable truck or backpack gun, though you’ll inevitably trade off some velocity and muzzle flash control compared to a full-length rifle.
