I was wondering, I am using air on my a-5. I have been doing some reading on the low-pressure kit. From what I understand it helps the a-5 handel the air pressure. I was going to go and install it and some one told me that I to by a regulator and something else to go with it for my tank. They told me it was to control the air flow. I thought that this is what the low-pressure kit was for?

Any help and or advise would be great.

Welcome to the forum.

The LP kit allows the gun to operate on lower pressure, in the 400-450psi region.

You will need a regulator to actually lower the air pressure into the gun to that range.  The regulator is not included with the LPK.

Might I ask what your goal/motivation is with the LPK?

The LP kit will not improve your efficiency.  The best way to do that is with an RVA or spring kit.

If your Cyclone stops feeding at 1,500 psi you have some other problem, however.  It should be good at least until 1,000 psi.

The LP kit can improve consistency/accuracy - or, more specifically, the LP kit will allow your regulator to do so.  While you can use a regulator without the LP kit, the LP kit gives the regulator more to do, so to speak.  But in the end you will still have a blowback Tippmann, and it is only going to get so consistent.

What the LP kit will do is noticably reduce recoil, which can improve your accuracy when shooting fast.  It will also dampen the noise report somewhat (but you will still be loud).

It will also make the gun harder to field strip, since you have to unscrew the LP chamber before stripping.  If you strip down in the field a lot, you might consider that.

I like the LP kit mostly for the recoil reduction, but if your goal is consistency and efficiency, I would start with just a regulator and RVA, respectively, and see how that works for you.

I am slow but what does RVA stand for?

As far as the LP kit. Thanks for the info. I am a mostly a heavy gunner so the loud sound works for me. I am looking into getting a pistol for when i need to be quite.

Empirically, I found no change in efficiency when adding the LP kit.  I have heard similar results from others.

Theoretically, there is more space - that's what the LP chamber is for.  More space, less pressure = about the same amount of potential energy.  The paintball requires the same amount of energy to push, regardless of the pressure level of the air.  Lower pressure means a slightly longer burst of air, but the same amount of energy expended on the task.  There could be some savings on the blowback portion of the action, since the LP hammer is lighter, but if there is I don't see it.

But for any given mechanism, simply changing the pressure level does not automatically change the efficiency.  It might some of time - for instance, using a regulator to set the pressure level at "just enough" to get everything working at the desired velocity allows you to minimize waste, but that is difficult to do without combinging the reg with an RVA.

So my next question would be, is the a specific type of regulator that I should be look for? This place that I get my tank filled out. Said they can doe it. The regulator cost 69.99. The did not give me any details.
