I'm gonna keep this to-the-point

I want to upgrade my BAR10 on a budget, this is what I want
150m/s spring
PDI 2nd sear

My gun shoots (currently) around 430-450fps according to the coke can chrono.
What bb weight do you guys reccomend? (i was thinking .3g??)

Will a metal spring guide and a new set pin be necessary?

Oh I also read somewhere the aftermarket springs have a wider diameter compared to the stock spring and require a new piston, is this true?

Thanks

As for bbs .3s are good for guns that shoot at around 500 fps

If you upgrade your spring, you'll want a new spring guide and piston because the stock plastic ones will eventually break inside the cylinder.

As far as I know, that isn't necessarily true because some springs are in fact longer, but not wider, but I guess that may depend on what you buy. I don't actually know if VSR springs are smaller in diameter than those in a L96, but if my assumption is correct any regular sniper spring should fit in your BAR 10 and even if the upgraded springs are larger in diameter, you would want to get a new piston anyways.

Hope this helps clear some things up.

If however you choose a PDI spring you will also want to get a PDI spring guide. I believe this is because PDI's spring have a different diameter then the stock one which means the stock spring guide won't fit the PDI spring. Obviously PDI isn't your only option, but PDI is very well known for having excellent springs as well as high quality parts.

If you have to trust one brand for compatability trust Laylax. PDI has some "bore up" parts and some PDI parts like other PDI parts to be in the same gun. As long as the spring says it is for the VSR-10 or pss10 (laylax label for vsr) you should be fine. As for bbs I recommend the .3s from bioshotbb.com. I also recommend you get a new piston and spring guide because the stock ones are just flimsy plastic. With a spring as strong as an m150 spring it won't be too long before one of them breaks on you.

Thanks for the replies. Will a new set pin be needed for the stronger spring?

Im probably getting the angel custom spring, are they any good?
EDIT:

ok so I measured and I can consistently hit a paper sized target at 125ft @ 430 fps with .2g bb. Is this good?

I Want to get to 200ft consistently, will this be possible with a 150m/s spring and a tuned hop up?

thanks

Why are you using .2g? Use .36 or .4 and you will have much more consistent shots, especially if you use a brand such as Super Grand Master or Madbull. ;)

I would use BBs around the .3 weight, I use G&G .28s, SGMs and bioval .3s through all of my rifles from 350 to 500 fps, as woogie said, its all in the hop as to how far you get them to go.


As for the spring, if your still using a 45 deg trigger I recommend you use 11mm springs, they are normaly advertised as this, most pro10 VSRs are 7mm springs as standard though I do believe the L96 version comes with 11mm (someone may have to correct me on this as I dont actualy own 1 or had 1 apart :shrug:), they fill the piston better and help prevent the stiff forward push on the bolt you can get from 7mm springs when the gun is cocked.


You may need to change the pin, but I'd only do it when the stock 1 breaks, so its up to you if you buy 1 and keep it for when the OE 1 breaks or just keep your fingers crossed that it doesnt :shrug:

I'd get an m140 spring, or even m130, instead and then airseal like a madman.
This will make your gun more quiet and you will not wear so much on the parts inside.

Pulling the bolt will be much easier with the lighter spring too, especially if you're not going to get a 90 degree trigger.
A lighter spring might not get you the same high FPS as the heavier spring would, but reducing wear and tear is good. But like others said, the hop and BBs are much more important than a heap of power. From what i have read, you should try an R-hop and the TDC-mod ("Top Dead Center" if i'm not mistaken) and you should see some positive results.

IMO, slamming in a new, hard spring is the last mod one should do to any rifle.

I agree with oiric. The stronger the spring, the more wear and tear. Therefore, your "budget" rifle becomes expensive quick by having to replace parts. Go with an m140 or m130 as he said, a good bucking, and spend a lot of time tuning your hop up. .29 SGM's would do you some good as well :tup:
