How strong of a spring can I use with your pistons?
You can use whatever strength spring you want! I have had people report back that even my 45 degree pistons have held up with use of 190 springs, for thousands of shots with no signs of wear. So, I would say try whatever springs you want, and dont fear killing the piston. Dont forget, your covered under a lifetime waranty!
Whats the difference in your pistons?
Single o ring pistons are the basic, yet still a great, strong piston! Double o ring has the chance to give better air seal/compression. The better the air seal/compression, the higher the chance for an FPS boost, more consitstant FPS, resulting in more precise, accurate, consistant shots.
Slotted pistons are for weight. a lighter piston moves easier, and faster. Resulting in a boost of FPS, and faster trigger responce.

What does this "Carry over" warranty mean?
Carry over warranty means, if you end up quitting the game, selling your rifle, trading your rifle, the parts you got from me are still under lifetime warranty for the new owner as well..
