no, this question looks similar to one i saw earlier, both rjr's and nasties will shoot 13.7 bps out of the box, what limits them is the board. they are both easy to shoot and come with the same triggers. here is what an lpr, tapeworm, and vff/hfv/hfa do:

A tapeworm is a solenoid restrictor. what it does is that it "retricts" are from being sucked away from the solenoid valve (which is what moves the bolt/hammer and makes the gun fire-the solenoid bolt can only do this with sufficient air pressure). what happens, is that when you pressurize your impulse, air fills up the valve cavity and the solenoid cavity (the valve and the solenoid valve air different-the valve puts air into the bolt and eventually get to a paintball, while the solenoid valve is basically, a seperate electronic valve that does what i said before). when the impulse is fired, the valve opens and air flows out of it into the bolt and out behind a paintball. when the valve opens though, it sucks air away and out of the solenoid cavity. what the tapeworm does, for 20$, is it restricts air from leaving the solenoid valve cavity, and thus the valve can't suck air away from the solenoid which in turn uses that air to move the bolt/hammer which is how the gun is fired.

I'll do you one better. a VFF (Voodoo Full Flow), a HFV (High Flow Vertical), and a HFA (High Flow Angled) don't do the same thing, but for 30$ more, they supply the solenoid valve with a consistant uninterupted supply of air that is at the same pressure as what the air is being regulated at the max-flo (or whatever inline reg you're using). an LPR supplies the solenoid valve with an uninterupted supply of air at a lower pressure than that at that gun's valve. why is that so good (in other words, why is an lpr so good?)? well, an LPR is the best because since it supplies the solenoid valve with air at a lower pressure than the air at the gun's valve, you can either:

1) Rase the opperating pressure of the gun (turn the inline reg up) and turn the dwell down (the dwell is how long the valve is held open-the longger the valve is open, the more air gets to the paintball, the higher the velocity is),

OR

2) You can keep the operating pressure low (120psi), turn the dwell up (keep the valve open longer), and turn the lpr's output pressure down.

The first list of things you can do results in less air being used and that means you get the more shots out of your tank (this is because less air is supplied to the paintball with the velocity staying at the same place that it would normally be because the pressure that is put behind the ball is higher than it normally would be and the dwell is turned down-valve is held open for a shorter amount of time-which results in less air being used).

If you do the second list of things with your lpr, you will use more air, (get less out of a tank), but you will also lower the bolt's operating pressure (which is the same as the solenoid valve because the solenoid valve is what powers the bolt/hammer). this results in less balls being chopped because not as much force is being applied to them because the bolt is being opperated at a lower pressure.

the only real difference between a nasty and an rjr is the nasty will get a few more shots per fill and they will look better/be a little lighter (no a noticable amount though).
