| Newbie Join Date: Aug 2008 Location: Toms River, NJ | bore size question im in the process of buying a barrel, and im not too sure what the deal is with the bore sizes of the barrels. obviously i know what bore size literally means, but my question is, why are there different sizes? right now i have an unmodified a-5 and i play woodsball. what advantages/disadvantages are there for going with a different bore? also, is there one that is kinda universal or standard? thanks. |

Sizers prevent roll-outs in closed bolt guns (pumps, Cockers, Palmers guns, etc) and they improve air efficiency some buy not allowing air to escape around the ball. The common size for most barrels is a .689.

Frankly, it really doesn't make as much of a difference as everyone will tell you. .689 is the closest to a standard you will get, and will work fine.

| MCB Member  Join Date: Apr 2006 Location: Syracuse, NY | Paintballs are .68 (ish) caliber. This does not mean that each brand of paint or each batch will be the same size. Some paint rolls right through a .679 Freak insert, some stuff won't fit in a .693 sized one. The idea behind barrel sizes and kits it to get the barrel that best matches the paint that you usually use. 10 yrs ago, it was generally considered that a .689 barrel was "med" , a 687 "small" and a .691 was large. Now most paint tends to be small and some "super small". |
