Buying Expansion CHamber?? Help??

[excetara2]

What expansion chamber should I get for my mag? I am looking for one that is in the 15 to 25 range. I was looking on ebay. That is easiest place to buy for me. How about 32 degrees 6 stage4 chamber, 8 stage x-core form DOP, Bob Long 6 stage expansion chamber, System X expansion chamber. Any other suggestions also. All those are cheap enough and I can get on ebay. Name any other good but cheap ones in that price range.
Thanks for any help.

Also will any expansion chamber fit on a mag. I am putting it on vertically where I have a gas-thru foregrip now.

It will fit, you'll just have to unscrew the gas-thru from the vertical ASA tho. If it's a big one it may not tho because it may hit the trigger guard, but that depends on what frame you are using to.

when i used c02 (last year), i used a tippman expansion chamber. i'm not sure how many stages it was, but it was smallish, not much larger in diameter and length than the agd bicycle type grip and it worked really well when combined with an anti-siphon set up. it also had a swivel base which was nice for line positioning.

i got mine new for $19.95 at a mom and pop shop.
