ORGA MAGNUS Spring APS2

High compression for MARUZEN APS2 + main spring for long shooting designed and developed by ORGA AIRSOFT.
Cocking is not too hard, and it has an exquisite power balance considering the burden on the trigger unit and cylinder.
It can be used for APS compatible bolt action such as MARUZEN APS2 and SW-M24 / CA M24 / WELL made in foreign countries.

* Please pay attention to the overspeed of the high-rate spring and install it at your own risk.

Purpose of spring replacement

Much of the purpose of replacing the main spring is to adjust the bullet speed.
The bullet speed has been lower than when it was new, or when it is new, but the initial speed is low, so you want to increase it.
On the other hand, although it is new, the initial speed is too high, so there are various reasons for wanting to suppress it.
In addition, it is common knowledge to replace springs with high cycle and long shooting customs, but it is also effective to replace springs due to spring squeaking due to spring resonance.

Features of this spring

Performance equal to high compression is achieved by making the pitch constant.
By designing the pitch width finely, the “sagging” is reduced, which leads to measures to reduce the initial speed when used for a long time.
Up to now, this is an excellent spring that has been proven by thousands of productions, including custom-made use and sales at ORGA.

Sufficient repulsion speed and spring length to prevent crash !

“Deflection”, which is often seen when the springs are expanded and contracted (including when they are not expanded and contracted), causes a crash as well as unstable initial speed and ballistics.

Other causes of crashes

* Extremely long / short spring
* If the diameter is too small or too large

What is an ideal spring ?

* Designed to allow expansion and contraction movement with the spring straight against the piston (no deflection).
* Repulsion speed after releasing piston is fast.
* Spring length and tension that can push the piston firmly during the stroke.
* All linear pitch springs with equally spaced windings.
* Optimal spring inner diameter that does not interfere with the piston inside or spring guide.

About initial speed adjustment

When replacing the spring, make sure to adjust the initial speed firmly and be careful not to exceed the regulation value.
The initial speed is related to the length and inner diameter of the inner barrel, the amount of air in the cylinder, and so on.
If you want to reduce the initial speed, shorten the inner barrel or drop the spring tension.

About the burden on each part

If a strong spring is incorporated for various reasons, the burden on the piston and trigger unit will increase.
In order to prevent premature breakage, it is recommended that pistons and trigger units be equipped with reinforced parts with improved strength.
