    Posted: 11 August 2004 at 12:40pm

could anyone help, i was wondering if the velocity screw on the A5 messes up the accurecy. I mean with  the air being restricted by the  screw rather than a regulated air input. it seems a waste of air and the turbulance caused by this screw could mess up the accurasy.

this probably dosent make sence too some but if it does then is there any way of getting rid off this screw.

im new dont laugh.

Think of it this way:

If you open up the screw all the way, and thus "stop restricting airflow", you will be shooting at an incredible FPS. If you hit the wrong person at that speed, you will have bigger problems than accuracy.

And, I think, accuracy goes down as you increase the velocity. I don't believe that, but I keep the velocity low anyway.

Also, I don't think that you can keep the FPS regulated just by using a Regulator. I never really thought about it. Anyone else?

Ok, here goes:
The "turbulence" does not affect accuracy. The long tube where the bolt slides completely stabilizes the air after going around the screw. Air doesn't bounce, it flows. Like water. Turn on the faucet at your house and hold a straw through the water falling down. It goes around it, then continues going down normally.

You *could* just use a regulator, but you'd still ahve to leave that screw in. Otherwise, you'd have a huge gaping hole draining air out and cutting down on the pressure, so you'd have to lose air efficiency to keep the fps decent. Plus, your gun could get hit on the hole and slop paint into your gun.

If you leave it in, you might as well use it, because the lower psi could affect re-cocking, the cyclone [A-5 only], or an R/T (if you have one). I'd say if it works, leave it. And it works, and does not cause "turbulence" that affects accuracy.

I'm looking in to the same thing. this week I have a few things to try one is to try different springs to regulate the speed of the ball. tried to get a rear adjuster but out of stock (I will get one).

You know the back of the gun where the two pins are that comes off and the bolt assembly slides out? Right behind the back of the trigger casing, under the MP5 rear sight- yeah thats it there- it just changes the tension on the spring and affects how long the valve is opened instead of restricting air flow.

I'm not 100% sure but I beleive a rear velocity adjuster can be more air efficient- the way it works is by volume- output capacity. Kind like filling a bathtub with a drain- if you have the drain opened all the way and turn on the water for 1 second, more goes down. If you have the drain half opened, the water goes out slower but uses the same amount- 1 second worth of water.

The RVA (Rear Velocity Adjuster) just changes how long you leave the bathtub faucet on- like if you leave the faucet on for .60 seconds instead of one second for the same flow output of the drain half blocked. Don't quote me on this, but I'm pretty sure.

Anyway, http://www.countypaintball.com

Just go to Google and do a search for one, or go to almost any on-line store that sells Tippmann accesories. You could also check your local proshop.

no need. after approx. 3" of barrel the air is perfectly evend out around the paintball no matter what, their wont be any bad effects from the velocity screw.

If your set on getting it out and keeping your marker at a safe velocity it MAY be possible with a Madman spring kit and RVA, but like I said the velocity screw doesn't hurt anything.
