Hey guys, today I am going to walk you through my process of polishing the internals of the Tippmann A-5. To start, I would like to note that this article will get us most of the way through, but I still need to go back and finish up the polishing. When that happens I will add a second part to this guide. I used the Brillo pad method for this review, but you can use sandpaper or a Dremel. We may cover these methods at a later date.
Some may ask, "Why should I do this mod?" I am glad you asked. Here are a few reasons:
1) Increase air efficiency
2) Prolongs the life of your o-rings
3) Reduce friction between internal bolts and the frame, providing a more slick and clear movement when shooting the gun
4) Most importantly, polishing your internals not only helps your performance, but it also helps you with your knowledge of your marker.
Ok, to start you need to disassemble your gun. You'll have to take it completely apart and take careful note of where everything goes (also handy to have your manual around). In case you have lost it, here is the schematics:

Here is a picture of the gun disassembled:
As you can see, the internals are painted black half way and have good amounts of over-spray on the rest.
To do this mod you'll need a few things:
1) A box of Brillo pads
2) Sink, Soap, Water
3) Loads of Elbow Grease
4) Oil for your o-rings
The first thing to do is to plug up your sink and get some water in there. Take one side of your receiver and dip it in the water, then dip a brillo pad in water and begin scrubbing on the internals.
Here is a few pictures of what you are trying to do:
As the blue accumulates on the receiver, just dip it in the water and wipe it off, or hold it under running water to rinse it then resume polishing.
Eventually, after a good bit of scrubbing you will get something that looks like this:
Once you finish polishing, you'll want to take some soap and water and really clean everything out. You will be amazed at how much dirt and grime there is in there.
After you have finished cleaning both sides of the receiver, you'll need to dry it off. You can use a hair dryer or towel, but just make sure its dry. After it is dry, apply oil to all o-rings and begin reassembly.
Congratulations, you have now improved your gun for a very small price. Now go enjoy your hard work and spray some paint.
