Has anyone tried this and could they confirm if it actually increases FPS. Wouldn't it also shorten the life of the piston because it would hit the wall of the cylinder harder? Also, if you cut it half way, then would cutting it only 1/4, leaving 3/4, increase the FPS just a little bit?

If you don't know what I'm talking about, watch this.

dont do it
just buy yourself some upgrades. then you are 100% sure of increase of fps!
alsow change the hopup rubber ASAP, the stock 1 i broke in 1 game in the winter ... so ... dont do the airbrake mod.

Yes it can be done. I did it with my bar and nothing bad happened to it. I think I cut about 1/4 of an inch off and all was well. There will be nothing wrong with you rifle if you do this. Just know that once you are done cutting you can't go back.

just make sure to sand everything down and clean up very good. You don't want all of that stuff going through your hop up.

PM me about all of the little stuff if you want. I have done just about everything that you can do to this rifle.

Thanks for the info; I'll keep that in mind woogie.

If you buy a Laylax pss10 high pressure piston for a VSR it comes with the ability to have either an air brake or not by simply unscrewing the brake and replaceing it with a grub screw. So you can experiment to your hearts content . Personaly I run air brakeless in my VSR as all it really does is make the gun slightly quieter and reduces the full potential of the gun

I was planning on upgrading, so that's good to know, thanks vindicareassassin.

It does work.. BUT and its a big but JG Bar 10 internals are weak as it is with the stock spring it comes with so more power is just going to destroy things inside it stick with what you have at the moment its like 400FPS stock isnt it? Im pretty sure thats good enough. Buy a spring guide / sears etc so your rifle can take the power.

I was told if i want a 130SP spring for my TM VSR G-Spec which is about 350+ FPS with 0.20's that i would need a spring guide for that and thats in a TM which are known for their great internals.

This is so useless modification IMO. The gun itself is way cheaper than an real TM VSR so you save already enough money from the gun itself so that you can use it to buy better parts immediatly.

MOD:
In airsoft going too cheap will inevitably make your gear crap up.

But if the young gentleman in question is on a tight budget, an extra 40 fps for the sake of cutting a piece of plastic on a part he already owns, is a good mod, is it not?

If i were to not cut any parts or do any mods that would potentially ruin the rifle later, what parts would have to be bought to increase the fps on this rifle?Ideally I'm trying to reach 450fps with a .30 bb

 

[vindicareassassin]

Just search the VSR section as they are essentialy identical, all the upgrades there are relavent for the BAR

Just a word to the wise, I know you are trying to reach 450 fps with a .3, but the ideal power to weight ratio is 380ish fps for any given weight of bb. Just something to think about, other than the fact the more you increase spring power the heavier cocking the rifle will be, which believe me doesn't sound a big deal, but try racking a 190 spring, while prone, and trying not to make to large a movement, its bloody near impossible

 

[jdocsniper]

thanks for the info, so given im firing .28g bb at 380fps, approximately what is the yardage in terms of distance and accuracy am i looking at? given a general rifle such as the jg bar or the vsr, sorry im still learning the science behind this sport.

171.16 feet without hopup. Used this article to get this info: http://www.arniesairsoft.co.uk/?filnavn=//articles/fps_limits/fps_calc.htm

I wouldn't pay attention to that article. Based on experience, without hopup your gun won't go farther than about 100 feet. Also keep in mind that the article/calculator didn't take into account wind resistance, and that the gun doesn't maintain a constant velocity but rather decreases in velocity rapidly once it leaves the barrel.
