Expo Arms 16" 5.56 AR-15 Lite Upper Receiver Group with Charging Handle and Bolt Carrier Group

Expo Arms Lite Barreled AR-15 Upper Receiver - 5.56 - 16" - XP-URG-V-556-16
The Expo Arms Lite Barreled AR-15 Upper Receiver trims weight from a standard 16" 5.56 build with a lightened top rail and slim M-LOK handguard, giving you a nimbler carbine without giving up mil-spec reliability.

Features:

• 16" Government-contour barrel chambered in 5.56 NATO, 1:8 twist
• Nitride-finished barrel
• 1/2x28 threaded muzzle with flash hider
• Mid-length direct-impingement gas system, 0.078" gas port
• 15" lightweight M-LOK handguard, center section of top rail removed

Removing the center section of the top Picatinny rail cuts handguard weight without sacrificing strength or M-LOK real estate, and the 1:8 twist handles the full common range of 5.56 bullet weights for a versatile all-around build. The mid-length gas system balances reliability and felt recoil for a 16" barrel. The 1/2x28 threaded muzzle ships with a flash hider pre-installed, and the nitride finish adds corrosion resistance without the weight of a heavier coating process.
