bushmaster pump question

[pookachu32]

hey, I finally hooked up some Co2 to my bushmaster pump and I was wondering how to turn up the velocity on these badboys.

[FESTUS33]

I'm not sure but if they're anything
like the Nelson based marker's,
it has to do with Hammer spring Tension.
Heavier spring More velocity,
Lighter spring less velocity.
Like I said I'm not sure.
I'm sure there are other's on this forum
who could tell you for sure.

I think you need a special tool to go down the barrel into the hammer/bolt and screw it out for more,in for less,I think.

Are you sure you're not thinking about the PMI III/VM 68

yeah.... um i'm not so sure on that spring theory. but I know their isnt a screw thing down the barrel like the phantom or anything. any one else got any input?

There were lots of guns that adjusted down the barrel,it was "the thing to do" of the time(late 80's).

if it doesnt have an adjustable bolt you can get a spring kit online or at your local store

look into gettin a adjustable bolt such as the one here http://www.skanline.com/productspb/a...verick_PB.html or these http://airsoldier.com/oldschool/index.shtml

most parts like these are interchangable as long as you get the ride style of cocking and check on pumpplayers.com or the phog and get a second opinion

Hey, I used to have one of these when they were top of the line! You need to change the springs inside. That is the only way to change your velocity

My Bushmaster came with the adjustable bolt. The thing you stick down the barrel is just a super-long allen key. If you can't find one you can take out the bolt and use a normal size one. I think its about 1/4" but I'm not positive. Go clockwise to get a higher velocity. If the bolt isn't adjustable you'll have to get different springs to adjust the velocity. You can also cut the spring behind the powertube to increase your velocity.
