Manufacturer: Bushmaster Model: M4 A3 Patrolman Carbine SKU: 90289 Caliber: 5.56 NATO / .223 Remington Capacity: 30 Rounds Barrel Length: 16" Chrome-Lined (M4 Profile) A2 Birdcage Flash Suppressor Stock: Black 6-Position Collapsible Overall Length: 34.75" Sights: F-A2 Style Fixed, R-A3 Carry Weight: 6.7 lbs Twist: 1:9" At the heart of the design is a direct gas impingement system. Gas is tapped from the barrel as the bullet passes by the port located above the rifle's front sight base. The gas then rushes into the port and down a gas tube located above the barrel and into the upper receiver. From there, the gas tube funnels into the bolt carrier. This gas system unlocks the bolt and begins the cycling process, but only after the bullet has exited the barrel. Direct impingement has several advantages over gas piston systems. For semi- automatic rifles with a barrel length of 16" or greater, impingement AR-15s are lighter, easier to free float the barrel, and much less expensive to manufacture. A 6- position collapsible stock allows the shooter to adjust length of pull to their personal preference, while the carbine length handguard provides steady handling. The buffer tube dimensions are those of the smaller diameter commercial spec. However, everything else about the Bushmaster is mil- spec. KNOW YOUR LOCAL AND STATE LAWS!!
