Well i am converting my CA M15A4 into a SPR. If you could tell me if you see a flaw or something that has bad quality then let me know! These are what I plan to put on it.

what spring are you using?

I forgot but I think it was a Guarder Sp-120 or 130.

with no air leaks you'll be well over 400. Not to sure where abouts but im at 390's with a sp100.

yeah when I give it to "The Drew" ill make sure to let him know that I need it to stay in the 370-380's. A new spring should probably do it.

i believe so... that looks like a m16 length hand guard but the outer barrel does not look like it extends out past the front site very far so unless you want to run a long suppressor (witch might not look bad) to cover the remaining barrel you'll need a different outer.

or just a different inner barrel right?

this is what its going to look like. http://www.airsoftgi.com/product_info.php?cPath=154_157&products_id=3168

yea im modeling it on the asgi's home page, also I do have the full stock.

Probably just a standard m16 length. This is one of those we'll figure it out kinda things. Might be m16, but there might be a similar barrel that is a close fit. Sig550 or M14.

Whats the teflon cylinder for?

I would assume because he know has a non m16 cylinder. Moar air!

I thought it said somewhere that his riffle was going to stay under 400 fps?

M4 cylinders are ported (hole in side)
