Did you try turning the knob in the back above the CO2 insert? You have to use the hex key...

Check your springs.
They are in the bottom chamber in the body of your marker.
Also, the place for you to adjust to the velocity is under the stock and is adjustable with your normal sized hex wrench.

Also, check if you have any damaged O-rings (those little rubber seals to keep the marker airtight).

Please post if you have any other adaptations on the marker.

1.turn your velocity adjuster in (metric 4 allen key)
2.buy a spring kit and use a stronger spring if 1. doesnt yeiled desired resaults.

Also remember, if you have trouble with the velocity adjuster, don't do what I did and strip the screw :(.

are you using HPA or Co2? if your using co2 get a stabalizer

Does ur MR1 hav a reg on it ? If so turn ur reg down or up whichever one lets in more pressure. Take the filter thing out of the ASA it might of been clog if you used CO2.

With your velocity issues, it is in your methods in adjusting most likely judging by your numbers. You need to fire 5 shots to reset the springs in order to get accurate chronograph readings. Adjust in a quarter turn at a time until you hit 300fps, then decrease it (take it out) an eighth of a turn and see where you're at. If you're hitting 280fps, drop it another 1/16th of a turn. You want to get the marker so that when it's adjusted it will hit a MAX of the field's velocity limit. The marker when in it's stock form with CO2 can spike, and you don't want it set so that when it does spike it destroys someone's equipment (more specifically, their goggle lens).

i always use air no co2 and i dont have any regulators

today i shoot 20 rounds with the velocity adjusted max in and 20 shoot haflway out and another 20 when velocity adjusted max out i have changed all the 0 rings and a stiffer spring and now the crono says about 150 fps 152 fps 151 fps ok but to low speed

any ideas???? plz help i cant play
