Because of the low fps,

[In terms of time? More least 150 hours...daaaaaaaaam]

What made the low fps?

If the original, even if no-piston spacer 750fps guaranteed.

Both around 500 fps
Best setting is 570, but forgot .. now .. 530]

With this money, I should have purchased CA sr25 ..
A & K sr25's industrial waste ....

Lower fps ..
The cylinder head was too short to think.
Stock equipped with Teflon tape so-modify the cylinder head.

But lower fps .. may be 480?

The really crazy.

However, around 500 ...

I see a forum []SDairsoft.com ? View topic - Long range AEG builds

If you are looking for such high velocity, then I assume you won't be shooting people with it (target shooting maybe?).

Why not get a pellet gun (air rifle)? I don't know about Korean law, but you can probably own a .22 air rifle which will pack a lot more punch than an airsoft gun ever will.

Airsoft isn't designed to go over 500 fps anyway really, it's all about being able to shoot other people safely. If you don't want to shoot other people then you should consider something else :)

That's right, I do not shoot a person.
In Korea pellets are difficult to carry.
I just, AEG maximum range of my "dream gun" I wanted to create.

Korea's law 0.2j ..
Creeps. I should not say it's the law.

bb gun ... We are dealing with criminals
South Korea's waste regulations.

I want to go to immigration.

0.2j absurd regulation ...

Your original post is a little difficult to understand but if you have a MS210 spring, and it is only firing at 530fps, then you are most likely getting a burst of air sneaking past the bucking.
The bigger the spring you use the more chance you have of a burst getting past the bucking.

Past burst ??
Burst mean ??
More chance?
I am stronger spring more chance?
This rather, ?? higher fps at a lower spring
