Upgrading TM VSR-10 G-Spec

[blmhawkeye]

I currently came into possession of this rifle and am looking forward to upgrading it to the fullest potential.  At the moment I have on my list of parts to purchase include the following

1x B↑Premier Palsonite Cylinder SET VC
-B↑Premier Palsonite Cylinder
-B↑Taper Cylinder Head
-B↑VC Piston
-B↑Spring Guide for VC Piston

1x Bore Up trigger set

1x 6.01mm PDI tight bore barrel

1x Firefly Hop Up Bucking for VSR-10 (Hard)

From my understanding I need a different spring than the normal upgraded spring that would go with a VSR-10.  I didn't have much luck unfortunately in finding anything on my own the last few days of looking through evike.com/airsoftgi.com/and trinityairsoft.com

I also did not find a bolt handle (saw a post on another site that it snapped while the shooter was cocking the gun but there were other reasons other than the resistance of the spring that caused it).  I'm wanting this rifle to shoot decently far and be around 515fps with a .25g, but from what I understand I could have a higher spring with more hop up on the pellets to get better accuracy/range and keep it in that fps if few posts regarding the matter that I've read on here are correct.

I'm looking for any suggestions and would very much like the assistance on locating parts if it is not to much trouble.

Thanks again,
Hawkeye

Edit: found an aftermarket Hop Up finally

Im a vsr10 owner and have it fully upgraded. I suggest getting an EdGI 6.01 ID bull barrel
http://www.edgicustom-usa.com/
Custom made excellent precision brass barrel. You can get a ported barrel for increased bb stability right when it exits the barrel. Look his name up you'll see vsr10/bar10 owners their review about his product.

if youre shooting to shoot more that 550fps on .20g bb then you I suggest the 9 ball hard type hop up works really well for my vsr. Doesnt jam and provides a good air seal even without teflon mods.

My TM vsr10
EdGI Custom Bull Barrel 5.98mm ID (435mm)
EdGI upgrade kit:
 Sp01 Spring and Metal Piston
 Spring Guide
 Trigger/piston Sear
 Spring Guide Stopper
 Cylinder Head
