Pretty much anything decent. PMI Premium works awesome in it. (No breaks so far). I wouldn't recomend getting any ZAP paintballs, cause I have had nothing but probs with it. JT Elite is pretty good, not as high quality as PMI Premium.
This barrel is awesome compared to my 12' Muzzle Brake Spyder stock barrel. It hasn't broken a ball on me yet! The stock barrel I had before chopped thru paint pretty bad. I was getting 3-8 breaks for every 200 or so paintballs I was using. Today, I went out and shot 700 rounds (using the same paint from the same box) without a single break. I was astonished. The accuracy of the Thunder Pig is great and it is quieter than the stock barrel.
Nothing so far. It is an incredibly good barrel for the price I paid.
Incredible accurate, high quality barrel. I won it off of an eBay auction for 15.50 plus S & H. You can't beat that price for the performace it delivers to your game.
Tippmann 98 Custom, Psycho ballistic double trigger, CMI dop forward, CMI regulator, stock barrel and anything else I can get my hands on
pmi - really anything NOT old!
Never had problem with barrel. Have used it for over 6 months & it's great. Shoots awesome everytime, doesn't break balls - I don't know why people have problems with breaking balls - maybe it helps if you clean barrel after every use? I love the internal rifling - no other barrel gets the accuracy or distance of the CMI's I have. If I need barrel shorter, I just remove end to take it down a couple of inches in a tight space - no problem! Also really light.
NOTHING! 6 months & still no problems
Keep this barrel clean & it's incredible for the price - I'd pay anything for it - I love it. Maybe it helps with a regulator - I go between my 14" & 21" a lot & adjust the pressure to get the best performance. Anyway, it's long, it looks cool, works great and is cheap. What more do you need?
stock standard barrel that came with my black dragun basic.
m3 Black dragun basic, custom expansion chamber 16 oz co2 flame drop forward microline remote...
I dont know yet...
hmm THe only good thing about this barrel is the shock factor that its 21" long.
ITs too long and lowers your fps too much , bran new it breaks every other pmi ball i shot...
After i cleaned the burrs out of the barrell and champhered the rough edges it stoped breaking balls, however it is still too long IMO anything longer thatn 16" - 18" is just too much and doesent add any accuracy or range + it slows down your fps. IF your looking for a gp better than stock barrell please look eleseware and you will have better luck than i did...
