View Full Version : Speed of your MR1?

06-19-2006, 01:19 PM
Out of the box I clocked my MR1 at 332 fps, any else had this problem? I've read on pbreview.com about the spring being a little tight when you first get your gun and a couple of people recommended a spring kit.

My only problem is that I won't get onto a field until next week and I need to know before that which way I crank my velocity adjuster to slow it down (I need to do this without firing a ball since I currently have no ammo).

Thanks in advance!

Screw it out to lower velocity. Get a spring kit when your at the field, and put in the lightest spring.

I too had the same problem. The slowest I could get it was 320fps.

I snipped the spring at the field, and then it wouldn't go faster than 150fps.

Bought a Shocktech spring kit. Worked fine after that.

Definitely buy your spring kit BEFORE you head to the field. I had to rent a 98C after I snipped the spring on my MR1. :(

I was shooting between 300 and 320 ...

but after 1000 balls...now i'm shooting between 250 and 300 ...

but i'll change my spring kit next time i go into a paintball store...

Just to be sure... ;)

Yup, that's another thing I was told, that the stock spring just needs to be worked in.

Doesn't help me when I'm sitting in the clubhouse at the field after already paying for 2000 paintballs at C$120! ;)

I guess I'm the one guy who didn't have to run out and buy a spring kit. Mine actually started off shooting around 240fps at first, and I had to crank it up to 280fps.

Hmmm... I may still look into a spring kit though... can't hurt to have spares I guess.

332 fps! That's crazy!!!!!!!!!!!! MIne might be the same. I havn't shot a single ball yet. When I bought the CO2 it was empty:(

08-06-2006, 02:55 PM
correction .... 332 FPS. Field regulations are usually 295FPS or so. I would stay at around 275 with co2, since at the end of the day you could wound up well over 300FPS.


BTW try not to bring back older threads anymore.

i bought the 32 degrees spring kit and put in the heavy one. mine was shooting 340+ fps, but since im using co2 i get fps spikes so once in a while i get 365, 380 etc. but ive never gotten over 400. this is with the velocity screw turned in about an 1/8

so... whats te best choice of springs kit to buy, i mean the brand, performance?

I had that same problem and all i did is took the gun apart(pulled the spring off) and took out the adjuster and it was shooting at 240. And after i was done playing i put it back in and it worked fine after. Try that and see if it works.

Out of the box, my striker plug/ velocity screw was jammed, but when I got a new 1 I had 280 fps

I'm having exactly the same problem, my marker is shooting at about 320 FPS

are there any the risks or problems if I dont fix this and keep on playing with this velocity?

320 isn't that bad if your playing woodsball or scenario games. They sometimes chrono at that.

Now if your playing indoors/speedball... thats a problem. It is very painful... but not at the extremely dangerous point yet.

Usually indoor chronos/speedball chronos want you to put your gun at 250-300FPS.

I will see what my MR1 shoots at when I get it... I hope I dont have the same problems.

my mr1 was hot out of the box clocking at 320 after a hopper of paint it was down to 260 now i have a hard time making 270 after shooing thru 2 cases

spring kit is a must
