|SILVER FRONT TIP ONLY! 18in barrel front for all 2-piece Evil PIPE barrel sets. Actually measures 12.5in long. Must be used with an Evil PIPE Back (NOT included)! This is just the standard PIPE Front Tip as shown. The threads will NOT fit a Spyder or any other marker without the Evil PIPE Back. Will fit any marker when you get the appropriate Back (NOT included). PIPE fronts have unique angled porting that not only aids in the cleaning of the dreaded broken ball it also reduces ball turbulence which results in a longer, straighter, more consistent shot. Micro hone finish tolerance: 2 to 5 microns. 30 degree angle venting, clears broken paint out and away, no more drips throwing off shot after shot (as often occurs with straight porting!) Evil barrels are used by some of the top pro players!
