Frequently Asked Questions (FAQ)

Do I need to modify my rifle during installation?

In most cases, no. Some models (such as newer JG BAR-10 rifles) may require minor modification due to different screw sizes.

What is the advantage over a standard 45° trigger?

The ZERO system uses a 90° piston sear that eliminates piston lift and canting inside the cylinder, resulting in smoother operation and a much longer service life.

Is this upgrade worthwhile with weaker springs?

Yes, although its full potential is realized with stronger springs. With lighter springs, the main benefits are improved trigger feel and greater durability.

Is trigger adjustment difficult?

No. The adjustment is easily accessible, and the inspection window allows you to verify the setting without disassembly. However, adjustments should always be made gradually and followed by proper safety testing.
