View Full Version : no velocity out of mr1. help

09-16-2008, 09:42 AM
I have a mr1 with a rocking trigger, alamo city low blow bolt, and 16" J&J barrel. I can't get any velocity out of it. I have put in a heavier spring and all the orings are good. The balls just don't get out there anymore. I can only get it ti chrono at about 245. I'm running co2 without a remote. Please help.

did you compare the low-blow to the stock one?

check to ensure that your airhose ect is not pluged, lub the marker well and out of curiosity what spring do you have in there out of a kit? if so what kit and what color of spring? this is an od problem seeing as how most MR1 shot way hot.

I would hook the Co2 staight to the gun and chrono. Maybe your remote line is cloged

I am not running a remote line. The gun gets cleaned and oiled every time I play. I had the red spring in which is supposed to be the heavy spring.

The only thing I can think off and I think its a long shot. What is your bore size too paint ratio. Maybe your paintballs are too small?

could be your valve isnt letting enough air through

Wow, so many sugestions from so many directions.... I don't know if you can do this in an MR due to it's design, but the best spring combination I've found for most guns is a medium valve and light main with regulator tweaking to get in the right velocity range. If you do not have a regulator (don't see it in your specs) swap your springs out for a medium main, medium valve, and see where that gets you. Then a light valve, medium main.
