Frequently Asked Questions (FAQ):

1. Is this barrel compatible with the L version (with laser)?
This model is intended for standard GEN1 and GEN2 versions. For the L version with integrated laser, we recommend purchasing the barrel specifically designed for that model to ensure proper alignment of the gun.

2. What effect does the 10cm extension have on shooting?
The extension prolongs the path where the propellant gas acts on the projectile, increasing muzzle velocity while improving accuracy at longer distances.

3. Do I have to use the included reinforced spring during installation?
Yes, the reinforced spring in the set is designed to compensate for changes in pressure and ensure reliable functioning of your gun's mechanism after the upgrade.
