With this barrel my tippmann shoots alot further and is alot more accurate.
Weaknesses:
If you break a ball it is even worse then the stock barrel
Review:
First the good
-First off it is cheap i picked mine up on ebay for i believe it was 15 dollars
-Acurate shoots almost as straight as my friends flatline but not as far.
Then the Bad
-If you break a ball in it you must clean it or your balls will not come anywhere near your target.
