12.7x42 (.50 Caliber) is one of the popular big-bore AR-15 calibers to take the firearm world by storm in the early 2000s. One of the first things you’ll likely notice when picking up a 12.7x42 round is the heavily rebated rim, which fits a bolt head designed for the 7.62x39mm cartridge. 12.7x42 is also an incredibly hard-hitting caliber that can shoot up to 400 grain bullets, making it ideal for hunting large game at short distances.
