"The front loading alum. sleeve, locks into place, securing it in position in the base of the barrel, eliminating any movement that could affect performance. The innovative locking system expands upon the basic barrel kit concept, by precisely aligning the bore of the sleeve with the bore of the muzzle. This attention to detail ensures seamless transition as paintballs move through your barrel. Sleeves are color coded and come in 5 bore sizes. An extensive honing process creates a mirror finish for consistent accuracy and maximum range."
