VSR/BAR build

First off I want to say, how glad I am this board is here. I'm relatively new to airsoft, and now a sniper role.

I have some ideas for a build, but I'd like to ask you guys to tell me what I might be doing wrong. And before anyone says it... I'm not trolling, and have done my own research but am simply trying to avoid any unneccasary spending like I did on my AEGs when I got them.

Here's my build

TM VSR-10 or JG Bar-10. - Can't really decide of the TM is worth the extra $$$.

Laylax PSS10 VSR10 Spring Guide - $27
Laylax PSS10 VSR10 Inner Barrel 555mm - I plan to add a suppressor I already have - $55.00
Laylax VSR-10 Silencer Attachment System (S.A.S.) -$19.00
Laylax VSR-10 Zero Trigger -$175.00
Laylax VSR-10 170SP Spring Upgrade for <550fps events -$21.00
Laylax VSR-10 Teflon Cylinder -$100.00
Laylax VSR-10 150SP Spring Upgrade - For <500fps events-$20.00
Laylax VSR-10 Cylinder Damper - $ 20.00
Nine Ball VSR-10 Hop Up Bucking $23.00

Total cost - $ $460.00 not including the gun.

Am I missing anything? Am I overkilling it? Is there a less expensive way?

Thank you in advance for your insight!
