what does it mean to seal up the exhaust on the lower receiver.

I read this on otters site.

you know on the maddman rocket valve, there is no spring kit available. so all you really need to do is adjust the main springs?

does this work as a better advantage than playign with 9 different spring combinations?

there's an exhaust vent in the bottom tube. Look at the pic on his site to see it. I thnk it's right behind the brass valve screw. You might have to seal it to keep as much pressure in the blowback tube to help it cycle properly. Thread it and add a screw with Teflon, just make sure the screw doesn't extend into the bore of the cylinder and remove any burrs from the unside before airing it up.

and what do you mean no spring kit available? Do you mean the 7 piece kit or a valve rebuild kit?

the rocket valve comes with its own spring

so i won't need to play with the valve springs anymore?

what if i don't seal up the port? is that ok?

the spring on the valve itself is the only one for it...and the only one the valve needs. The other springs are for the striker so you can tune it. It's recommended you get them.

and no, you won't necessarily have to seal the exhaust port...unless you have recocking issues (as in it won't recock at lowered pressures.)


Fine tuning the SRP is what takes time and effort. To to the Madmann site and really look at the instructions. Print them out and make SURE you understand them FULLY before messing around with grinding the cupseal pin down
