Your plans to complete that AR-15 build project are finally underway. You've managed to complete your lower assembly, and it's time to check this project off your to-do list by completing your upper assembly. Since you've been killing it so far, we wanna help you out. You install the backup sights or optics of your choice, and do up your upper assembly.

This prebuilt upper assembly shows up at your door with a lustrous 16-inch stainless steel barrel and made of 416R Crucible stainless steel. The barrel is chambered in .223 Wylde, so it'll reliably accept both .223REM and 5.56mm NATO rounds. It's been matched to a 13.5-inch free-floating MLOK handguard. It also comes with the charging handle and BCG. All you need to do is install the sights or optic of your choice and then mount it onto your completed lower assembly. 

PLEASE NOTE: This is a prebuilt upper assembly only. It includes an assembled upper receiver, bolt carrier group, and charging handle. 

Here's the beginner's guide to 80% lowers.
