The Lapco A5/X7/Phenom/BT-4 Accushot 3 Barrel Kit 12 inch.
The classic Lapco One Piece Big Shot is still a favorite among players looking for superior performance. Lapco uses only Military Grade, solid, raw material. By doing this they avoid the waviness or lines that you see when you look down a barrel that was machined from raw tubing. The waviness and lines cause a paintball (which is not perfectly round and filled with liquid) to catch or spin causing those unwanted wild flyers.
Lapco hones their barrels in three stages. First, they are rough honed removing only .001 inch at a time from the barrel wall, to get them close to the finished size. Then they are semi-finished removing another .00025 of an inch from the barrel wall and creating a smoother finish. Finally they are master honed to create a finish that is smoother than glass and is perfectly sized. This gives the barrels the self-cleaning properties that will keep you in the game.
If you are in the market for a higher end barrel you are not going to get a more accurate barrel than a LAPCO One Piece Big Shot. You will save on paint (accuracy) and air (extreme low friction) with this well-crafted barrel.
