ACTION ARMY T10 reinforced spring for bolt action.
AAC T10 is for domestic setting and the initial speed is set low, so it is recommended for those who want to lift only the initial speed.

It was 85m /s at 0.25g when it was assembled in a boxed T10 and measured, but please understand that there is an error depending on the individual of T10.
T10S tends to have a low initial speed due to its short inner barrel.
* When changing the spring, be sure to measure the bullet velocity and make sure that the regulation value does not exceed the limit.
If over, decelerate by cutting the spring and tune at your own risk.

ActionArmy T10 internal details

The internal is completely VSR compatible, so any reinforced parts for VSR are compatible.
The inner length is 430mm, which is the same as Pro Sniper, and the cylinder can be easily disassembled. The spring is the same as VSR, and PDI's reinforced New trigger can be used.
The cylinder diameter is the same, so you can use a PDI cylinder ! (PDI pistons have different spring diameters !)
