Hey, im new to the forums, I just bought an mr1 from my local shop and i was wondering if anyone here happed to know what the approximate velocity range on the mr1 is. I'm just curious if i can use my gun at a local feild without havin to buy a spring kit or cut mine, because im planning on going early next week. Thanks in advance.

It depends on your air source, Co2 or HPA. In general anywhere from 200fps up to 400fps.

Co2's pressure will change with the weather & rate of fire. HPA has a built in regulator that will have an output in the 800psi range.

A spring kit never hurts anything. I want to say the velocity adjustor on the rear of the marker has an adjustment range around 50-75 fps.

alright, currently running co2, well eventualy upgrade but my marker came in a kit with a tank so im just gunna run with co2 for a little bit. I will probably buy a spring kit anyways. Thanks for your reply.

um, you should be able to shoot at the field speed limit without buying anything for it. it wouldnt make sense to sell a gun that doesnt shoot around 300fps out of the box...

my feild limit is 275 im pretty sure, so i was j/w if i can get below that.

All you need to do is just adjust your velocity using that adjuster in the rear.
Spin it counterclock wise to make it higher, and clock wise to make it lower

with mine stock out of the box I couldn't turn it down enough. I had to clip my spring. Once I was able to buy some springs, I did.

Yeah see that what i was worried about. Well my feild has a pro shop right there so if its over their limit then i'll just buy a spring kit. Thanks for all the help.

my MR1 came out of the box shooting 320+

heard that its a common problem. if you have to clip the stock spring, definitely invest in a spring kit and toss the clipped one.

so did you clip the spring or buy a new spring kit?

how much of the spring do you cut off?

how much of the spring do you cut off? I started with clipping. That method sucks. The reason it sux is because it is trial and error. Cut too much and you can only turn it up to 250 fps max. Which I guess is better than 350:p . The best way to go about it is GO SLOWLY. Don't cut too much of the spring. Only cut 1/2 to 1 full coil off at a time. If you have access to a chronograph (which I guess you do because, why would you cut the spring if you couldn't chrono it?;) ) and the time, don't be afraid to put some paint through the gun. Don't shoot 3 or 4 balls and cut some more. Shoot a bunch. Crank down on the velocity adjustment. Crank it in and out. When you get close to 300 fps cut a little less than 1/2 coil. Take you time. I can't stress that enough. When I finished cutting on my stock spring I had probably taken close to 3/4 of an inch off. But I also had a hard time getting it up around 280 fps. With one cut I went from 314 fps to 260 fps. I guess I cut too much. But it's better than hurting some one. I would rather shoot 200 fps than hurt some one.

In the end I replaced the spring. That is the best method. My friend had about 10 springs so we just found the correct one that worked well for me.

just got home from my local field, just lettin everyone else know that my stock MR1 shot 319 fps(field limit was 250fps), so you will need a spring kit if you wanna go play at some places.

not that im worried about it, but has anyone been caught with too high of a velocity? if you were, what can happen if they catch you?

well last night i went to a local indoor speedball feild and they didnt even chrono anyones guns, i was over by a bit and i was playin, no one said anything, but im not sure what they would actually do...they'd probably make you lower your velocity adjuster if you can or make you get a spring kit for your marker.

That is my point, i have never seen anyone make a big deal at a field. what are some good spring kits for the mr1?
