......how a coaxial works?............

cmon man at least research abit

I hate to be the bearer of bad news, but Spanerman, Spud Wiki doesn't explain to him how it works.

Here, try this site and BC Vids. Under BC Vids, try looking at the barrel sealing piston video on how to build a piston, and try searches on "barrel sealing piston" as well. You should be able to find what you need.

No but a simple search would of done it.....



is off the wiki....seems pretty explanitory to me

co axail just means the barrel is inside the chamber

I didn't see that. Alright, I take back what I said. Oh and Spanerman, I apologize if I sounded a little "snarky" in my message. I just re-read it and realized how jabby I sounded.
