5.56 AR 15 Upper Assembly – 16″ Nitride Barrel, 1:7 Twist Rate without Handguard

Description

A “naked” 16-inch upper that’s ready for a custom build.

This “naked,” barreled 16″ upper ships assembled without a bolt carrier group, charging handle, or handguard — it’s the perfect barreled base upper for building a custom setup, while avoiding “factory” components you’ll replace anyway!

Long-range performance is easily derived from this upper’s 4150 CMV, nitrided barrel, which features a Government profile that balances weight and accuracy.

NOTE: Does not include handguard, bolt, or charging handle.

• Grab a charging handle!
