The VKTR VK-1 Complete AR-15 Upper in 5.56 NATO with a 10.5-inch barrel and Sniper Grey Cerakote (brand part no. V-4027-3410-009-RP) is a compact short-stroke piston upper. VKTR Industries builds the VK-1 around a patented low-profile piston system and a thermal fit forged upper receiver, with a 9.85-inch low-profile M-LOK handguard to match the short barrel. The heavy profile barrel carries machined cooling flutes, a nitride finish and a 1:7 twist, and it is threaded 1/2×28. It is a complete upper only, ready to drop onto a compatible AR-15 lower with the buffer and spring included.

Key Specifications

• The chambering is 5.56mm NATO, the standard AR-15 cartridge with wide ammunition availability.
• The barrel length is 10.5 inches, a compact length for close-quarters handling.
• The handguard is a 9.85-inch low-profile M-LOK, sized to the short barrel.
• The operating system is a patented low-profile gas piston, which keeps combustion gases out of the receiver.
• The twist rate is 1:7, a common rate for heavier bullets.
• The barrel is threaded 1/2×28, the common thread pitch for muzzle devices.
• A carbine buffer and spring are included, so the buffer system comes with the upper.
