Side-Charging .223 Wylde Upper Assembly with 16" Parkerized Barrel and 15" M-LOK Handguard
Want a ready-to-run side-charging AR-15 upper without sourcing and assembling every part yourself? This one arrives fully built. At its core is a 16" M4-profile barrel in 4150 chrome moly vanadium steel with a 1:7 twist and a .223 Wylde chamber. The Wylde chamber is the key feature: it runs both .223 Remington and 5.56 NATO safely, so you can shoot whatever ammo is on the shelf and still get tight groups.
Up front, a lightweight free-float 15" M-LOK handguard gives you plenty of room for a light, bipod, front sight or any other accessory you want to hang on it. Everything else is mil-spec, including the M16-profile bolt carrier group, which works with the side-charging setup with no modifications, and the forged 7075-T6 flattop upper receiver that houses it all.
What's Included
This is not a firearm. It includes an assembled upper receiver, bolt carrier group and charging handle. Just add your sights or optic and mate it to a complete lower.
