10 inch barrel with a .689 bore for medium paint.

All LAPCO barrels are billet machined. They do not use tubing to make their barrels as many other paintball manufacturers do. LAPCO barrels are gun-drilled and micro-honed to exact sizes leaving a near mirror finish to make them the smoothest, most accurate barrels available. Other manufacturers barrels vary in size down the bore, creating wave like distortions. LAPCO barrels are so straight that they even clean faster and easier, making them the best barrels for the money. The unique counter-bore and porting pattern keeps gas pressure behind the ball where it needs to be and bleeds the pressure just before it leaves the barrel to help increase efficiency and accuracy.
