RPS Premieum, All Draxxus/Diablo-Thats all that fits.
None, for price
This barrel is the best barrel you can get. Why the price. I got mine Old Skool at Pevs for 45$ but this barrel can be bought for as low as 25$ in which case is better. I had bought a 12" Teardrop and thought of others. I returned it and tried the 14" CP 1 piece and it improved a lot more! The barrel is quiet and can shot with in a 3" Radius. I have never broke and can play all types of games.
I had some trouble but if you want pin-point sucess with this barrel use the RPS Premium. It's cheap and good. I have bought 10 barrels and the only barrels that came close was an 16"Armson Stealth and a 16"All American and a 13" Nyte Stikk.
So If you like a cheap Meduim-Tourney Grade Paintball Barrel then buy like 2 of these for speedball(10 in") and woodland games(14"-16").
Well my counclusion?If you didn't read my review here are the main facts.
-THIS BARREL IS THE BEST FOR ANY PRICE RANGE! Buy 2 and you'll be happy.
and maybe a 16" Armson Stealth
