300 Blackout AR 15 Rifle Kit – 16″ Parkerized Heavy Barrel, 1:8 Twist Rate with 15″ M-Lok Handguard, Side-Charged

Please note: We strive to provide the most accurate photographs of our product wherever possible. Due to availability limitations and supply chain constraints, slight variations of the handguard of this upper assembly may occur in the aesthetics of the skeletonizations in between the M-Lok sections.

This awesome build kit comes to you with a prebuilt upper assembly chambered in .300BLK. The barrel itself is made of 4150 chrome moly vanadium steel and has a 1:8 twist rate. It also comes with a 15″ M-Lok handguard for all your tactical accessory-mounting needs. The coolest thing about this kit is its ergonomic side-charging handle: Reach to the side and pull the handle back instead of using the charging handle at the rear of the Picatinny rail.

What’s Included

This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock.
