Less movement required = higher ROF. Pretty simple concept.

When you do this, consider the length of your inner barrel and where your cylinder port is. You may be able to remove more teeth off your sector gear. Or you may already be removing too much. Find out where your port is, where the piston head will be when compression begins, and which teeth are still connected between the piston and sector gear at this point. The teeth beyond this release point can be safely removed.

Yes, using a heavier spring will return the piston to battery faster - in normal guns. But when you begin to reduce the piston stroke, that can make up for issues of raking teeth. To be honest, I *think* you may be able to get away with a stock, M80 or M90 spring with such a setup. I'm not 100% certain as I don't have any hands-on experience, I only know the theory.

Easiest way to find out is to just pick the FPS you want, set it up and see if that ROF is acceptable to you. If it's not, reduce the spring tension till you find the velocity you like, run it for a couple thousand rounds and then check the piston teeth for any excessive wear. Biggest signs are the first three connecting teeth of the piston. (negate the 2nd one in your case since you're removing it.)

I'd actually recommend keeping the 2nd tooth intact. If you see it getting chewed up, then your ROF is too high for the spring. See if you're able to shorten the stroke more, and if not, then you should upgrade the spring rather than remove that 2nd tooth.

Fair enough, will add the info to my "knowledge base". Lol, thanks Bri.
