VSR-10 tightbore fps increase
 

I've got a question for all you VSR-10 owners:

What was the fps increase after you installed a tightbore? I'm going to be getting one and want to know what combination of upgrades will get me to about 450 fps.

Thanks.

Tightbores are more for accuracy than FPS increase. They should complement other upgrades rather than be relied upon to increase BB velocity.

15-20fps is usually the amount.
Also if you teflon tap the area around the hopup to make a better seal it will increase the fps a bit more.

I realize that, I was just wondering on the fps increase so I don't buy a spring that will push it over my desired max.

Thanks bean for the info.

If you're making it to the scrims this weekend I can show you mine which shoots ~445fps w/ 0.20g. I used the following:
VSR-10 G-Spec base, PSS10 130 spring, PSS10 430mm 6.03mm tightbore, teflon taped hop-up unit and I cut the air brake off of the stock piston.

I can't make it out this weekend, but maybe another time, when I get the gun maybe I'll hit you up for some advice on upgrades :D
