[Party of A-5]

Have had this marker sitting around for a while and after playing a few games with it I figure it deserves a lil more loving before it joins my arsenal full time.

First off does anyone have a scan of the manual? Mine came without one and I could really use a copy.

Next, what exactly is the rail on top of the marker. Is it a 7/8 or what?

And lastly what can I do for a better barrel for it? I know that pretty much the only choice is one that tippmann made (14'?) but do you think palmers could whip one up for me? Shouldn't be too hard, I mean it is a slip fit.

Thanks allot,
