This 7.62x39mm upper is built to punch hard and run smooth. At its core is a 7075-T6 forged aluminum mil-spec upper receiver, paired with a 7in MLOK handguard from ABC Rifle Co, machined from durable 6061-T6 aluminum. The 7.5in 4150 CMV barrel sports a 1:9.5 twist and is capped with a classic steel A2 birdcage flash hider. A 6.75in stainless pistol-length gas tube and .750 low-profile steel gas block keep it cycling reliably. The nitride 8620 BCG is full-auto rated with a 9310 7.62x39mm bolt and enhanced firing pin.
