The Greatest Truck Guns! The Choppers! But what caliber is best?
This review compares three short-barreled AK variants: the 5.45x39mm Krinkov, a 5.56x45mm Arsenal SBR, and a 7.62x39mm SAM7K. Despite its short barrel, the 7.62x39mm SAM7K demonstrates superior ballistic energy retention compared to the 5.45x39mm and 5.56x45mm variants, making it the most practical truck gun. The 5.45x39mm is noted for aesthetics, while the 5.56x45mm offers gentler recoil and uses common ammunition.
