Barrel Kits

Barrel Kits

Most paintball fields and tournaments require you to use their paint. Standard paintballs are .68 bore, but the actual bore varies anywhere from .674 to .698. If your paintball gun barrel is too small for the balls you're using, you'll break more paint. If your barrel is too large for the paintballs, you'll see a dip in consistency and accuracy.

To get the best possible shot, we recommend that you use paintball gun barrel kit. Barrel kits contain inserts or barrel backs that come in different bore sizes, allowing you to closely match the size of the paintballs you're shooting with the inside bore of your paintball gun barrel.

Planet Eclipse and HK Army both offer excellent paintball barrel kits, suitable for any paintball gun that uses Autococker A/C barrel threads.
