Additional mods to do for my MR1

[Nobodytoyou]

So far iv already done a considerable amount.

MR1 (a.k.a. Old reliable)
mods and additions
CCM Clamping feedneck
16" CP 1 piece barrel (0.689 bore)
Empire Prophecy Loader
Spyder Skeleton Stock
Kingman Rocking Frame 2.0, with a Virtue Spyder board
32* mangaport valve
shock tech spring kit
GUERRILLA Air 62ci 3k HPA tank
Dye Sticky Grips
also a bottom line ASA adapter

so far i plan to do this next

Add a regulator
get a barrel kit
*this is a maybe depending on if everything can fit*
get an eye compatible mr2 body to put everything in so i can finally give the damn thing eyes XD (not comfortable milling it myself)
change the valve assembly to the madman rocket valve (i hear many good things)
Change the ASA to a DP RAPS II ASA http://www.ansgear.com/Dangerous_Pow...s2asablack.htm
Tiberius Arms Tri-Rail Riser , so i can mount a scope and green laser sight (scope not for aiming but for target spotting at longer ranges when enemies try to hide)

anyways here's where i need a bit of help , as far as regulators go i wasn't sure if i need an adapter or something to put a reg on the mr1 body , i know ill need one for the ASA to switch to macro line

next any suggestions on barrel kits , preferably on the cheaper side of things (I'm hoping for sub 150$ http://www.ansgear.com/TechT_iFit_9_...9pc-spyder.htm <--- currently looks like a good deal but id prefer a few opinions

for mr2 body , i know SPPS sells em pre-milled , i just don't know if the internals match

and as for the madman rocket well i just like hearing others thoughts ^.^

also does anyone know if the newdesigns highflow valve pin will work with the 32* magnaport valve?
