Description
The 5.45x39mm BT (7BT4) cartridge is specifically crafted for rifles like the AK-74. The designation 'BT' originates from the Russian term 'Boytsovaya Tip', meaning 'Armor-Piercing'. Featuring a pointed steel core embedded within the projectile, the 7BT4 variant excels in penetrating armor. Widely adopted in military settings, this ammunition offers enhanced penetration capabilities, rendering it highly effective against armored target. It servers as the preferred option in combat situations where overcoming protective barriers is imperative.
