stock(cheap $40 adjustable i bought)
crossfire air tank
anything bigger than .688
i found this stuff to be great. I bought it at my local store for $30 a case(its known as crappy brown box)
im just going to say this right now, the shell is strong and holds up in my flatline(everybody knows they are VERY picky on paint)
It has a nice bright fill, and I have had no problems with cheaters trying to wipe it off so i dunno how well that stuff stays on. sum people say it has a runny fill, but what do you expect for $30?
Good buy. Mainly for recballers(like me!)
If you're going to a tournament invest in higher quality.
