i use an empire timmy. i used to use a a-5 with e-grip and rear velocity ajuster
Strengths:
Easy to assemble
Quick velocity change
Weaknesses:
Can easily fall apart
Review:
Makes things easier. The main problem is that it fell apart once when i was playing woods ball and i had to dig through the leaves and such crap to find the back screw and the spring. The thing is that while firing since its a screw the kick can cause it to unscrew. So you have to watch it.
Conclusion:
Don't buy it. It is to easy for it to fall apart or start lowering the velocity.
