LEVIATHAN & AVENGER | Same product different names and different valve systems performance 

I found something very interesting when I toke Nova LEVIATHAN apart to see the difference between my Air venturi Avenger and I noted that the spring, valve and valve seat and are total different. And And it seemed to me that Nova LEVIATHAN has more Air flowing and smoothly. To make sure I toke the valve system from Nova LEVIATHAN and assembly to my Avenger to do some shooting through the chrony to see what speed can gain with my previous tune with Jsb 18.13g@896fps AV without changing nothing And the result was 32fps gained...
