FPS Ideas...
G
I've been pondering this alot lately. I might buy a JG BAR-10 G-Spec for $115, and was wondering what upgrades should I use to get ~350 FPS with .36s or .43s. Also, what would be the "quietest" set up to run with?

Would there be a way to get ~350 FPS with .36s or .43 BBs?Cheese Man said:TK, 330 fps/.2, ~220 feet effective.

It would help to tell us what FPS you want with .2's not .36's or .43's because its alot harder to calculate potential upgrades.
Maybe 290-310 with .36s or .43s, but nothing that high.
You would need a spring that shoots 480fps with a .2 to shoot a .36 with 350 fps.
And a 510 fps spring woth .2 to shoot .43 at 350 fps.

Hope this helps.

^Really? Wow. Anywho, at that point, you are at the level that most of us have our guns at anyway.

So basically, it would be a completely upgraded rifle? Then in this case, I'll go with the 480 FPS spring with .36sCheese Man said:^Really? Wow. Anywho, at that point, you are at the level that most of us have our guns at anyway.
You might want to check in with some guys who know more about this.
I'm not saying i'm wrong with the calculation, but I might have misunderstood the math.
If someone could check it with that math link thing I send.
Don't want to feel guilty if Cravona ends up buying the wrong spring and spending $ on a too low/high spring.

Don't worry about it. I'm not planning on doing this until I've heard from someone who is REALLY good at math to help figure this out.pvt13 said:You might want to check in with some guys who know more about this.

Well the math itself is pretty simple. It's just a matter of KE = 1/2mv^2. You find out what the KE is with one bb weight, and then find out what the FPS should be with another weight bu substituting KE and m back in, just with the new weight this time.
Then I think I'm right.
I put the .36 at 350 fps, that gave me x joules, with those joules, I went to the bottom calculator and put .2 with x joules and it gave me how much fps it would be.
