Compressed Air w/ Lapco Dropforward
Uses a lot of paint (if you think that's a weakness)
I was skeptical when the person at my local paintball shop showed it to me. He let me test fire an A-5 with both CO2 and compressed air. I was sold, I bought it right there. I let him have it for a day so he could install it and dial it in for me.
When I played with if Saturday night, it was dialed in perfectly. I unleased a hellacious amount of paint. I rarely used a hopper before per game, now I was using a hopper plus two 140 round pods. I love the thing it makes a BIG difference.
One suggestion, just have an airsmith or a qualified person install it and let them dial it in!!!
I let my nephew use it for a few games and he is was amazed at how awesome the gun works.
You can use Nitro just don't believe all the negative hype.
If you wanna shoot faster than just the standard semi-auto buy it. I have no regrets! The gun rocks. And I did not chop any balls!
