Lapco starts out by their BigShot barrels out of single piece of high-quality, aircraft grade aluminum. As a result, the bore size and barrel wall thickness remain concentric and consistent all the way through the barrel. Thanks to Lapco's 3-step honing process, every BigShot barrel has a friction free, mirror finish that helps improve your marker's range and accuracy. The self-cleaning mirror finish also allows you to shoot through barrel breaks. On the outside, every Lapco BigShot barrel is bead blased for a durable, non-reflective matte black finish. We recommend Lapco barrels to any player who want's a high-quality paintball barrel made to military standards.
