KJW M700 Upgrades, wondering if this is what I'll need
 

I am planning on getting the M700 (not the take-down version), and from the research I've done, it seems to be a good rifle, but needs a tightbore and better hop-up rubber, so these are the parts I figure I'll need, I've already got a scope. I want to know if this seems good enough, and if the PSG-1 barrel will work in it, because I know they're different, but I just can't find how they are, believe me, I've looked. I think the M700 has a 650mm-ish stock barrel.

A suppressor (Doesn't matter what one, as long as it's ~55mm, which is most of them)

Uhhhh....unless the KJW has a totally different inner barrel and hopup than the Tanaka that it's cloned from (I have a Tanaka), there's no way an AEG barrel is going to work.

Yeah, it has a totally different barrel/hop-up assembly, but it's a clone other than that, it can take AEG barrels, which makes things easier. How is your Tanaka anyway?
