Stock 98 barrel - garbage
Lapco 14" BigShot - one of my favourites for the 98, much more accurate
Proto 12" 2 piece barrel - my favourite at the moment
Black Proto M6
Black Empire Reloader B
P.E. 68 ci, 3000
RPS Premiums or other high end paintballs. If you use any cheap stuff, it will just shred in the barrel and make a mess.
This barrel is alright. It allows you to not have to arc the gun, and that's basically it. I personally despise this barrel. Only 1 out of 10 shots fire like they are supposed to. This is because every paintball has minor imperfections, and every shot fires a little different. When the thing works, its like a dream.
This barrel is extremely loud. This is because it has no porting. It also has a very distinct 'ping' sound. Everyone will know you weild the flatline.
Paint constantly shreds in the barrel if you use cheap stuff. Use paintballs with thicker shells and very little oil. A battle swap is highly recommended.
The barrel is very time consuming to set up. The entire gun must be taken apart to fit the adapter in. Dialing in the barrel takes forever to get just right, then you have to hit it making sure there is no gap between barrel and adapter, or else you will shred paint.
The plastic shroud on the gun is crap. It cracks easily and is warped.
This product is garbage. If you get this because you don't want to arc your shots, suck it up and learn! A straight barrel has a very consistent arc and is way easier to aim.
