Battle of the barrels! Grimburg A5 vs TCR A5! 

Head to head comparison of the Byrna TCR (Tippmann) 11 inch, A5 barrel vs the Grimburg 9inch A5 barrel.
Grimburg barrels are known for their exceptional power output for only a 9 inch barrel. With the growing resurgent popularity of the Byrna TCR (formerly Tippmann TCR), there have been more reports of it's 11 inch barrel being more accurate and delivering far more power.
I decided to put these two together and test them both through a Valken M17.
to my surprise, I received minimal differences between output numbers of both barrels.
before I uploaded the video, DK Spencer of DK Spencer's Custom Kinetics ironically ran the same test using the Byrna TCR and was able to achieve far different numbers showing the TCR Barrel providing upto 20 joules of energy improvement over the Grimburg, so I obviously had to do the test over using the same launcher, my own modified Byrna TCR.... and lo and behold, was able to duplicate his findings.
so which one is the winner? wait until the end:-)
