PRO2A 10.5" 450 Bushmaster 1/24 Carbine Length Melonite M-LOK AR-15 Upper with Flash Can

Description

The Pro2A Tactical 10.5-inch .450 Bushmaster Carbine Length Complete Upper Receiver assembly featuring an integrated linear Flash Can packs devastating thumping power into a compact and highly maneuverable platform. Hand-assembled and quality verified in Georgia, this system is optimized to push the substantial concussive muzzle blast of the massive .450 Bushmaster cartridge forward away from the operator. With a premium Melonite-finished big-bore barrel partially shrouded by a slim, free-floating M-LOK handguard, it provides a seamless tucked look and excellent ergonomics for brush hunting, close-range defense, or heavy tactical tracking.

Key Features

Forward Blast Redirection: Outfitted with a slimline aluminum linear Flash Can muzzle device that channels loud noise, massive flash, and heavy concussive pressure downrange away from the shooter and bystanders.
Thumping Big-Bore Power: Delivers the immense kinetic energy and stopping power of the .450 Bushmaster cartridge out of an agile 10.5-inch barrel configuration built for quick tracking in dense cover.
Standard 1/24 Twist Stability: Engineered specifically to stabilize heavy straight-walled big-bore hunting and defense rounds for absolute accuracy at close-to-medium ranges.
Aggressive Tucked Aesthetics: The linear flash can sits partially shrouded beneath the free-floating 12-inch M-LOK rail system, maximizing rail accessory space while establishing a flush silhouette.
