Big-out Original Junior Detune Barrel (for Gas Blowback)

Detune your gun and enjoy airsoft with your children!
Turn painful indoor and CQB close-quarter battles into fun games!

*This product is a custom part for advanced customizers.

This is an adjustable custom part intended to detune an 18+ gas blowback handgun to a 10+ compatible gas blowback handgun with a power output of less than 0.135J by simply replacing the inner barrel of a Tokyo Marui gas blowback handgun compliant (compliant means a product with the same shape, such as a copy) hop system with this product. (Detune means to reduce the power of the original product.)

Furthermore, the inner barrel is stippled to improve the stability of BBs during firing.

※Please note that this is a custom product. We do not guarantee that simply installing it will result in an output of less than 0.135J.

(Manufacturer data) As a test, we fully opened the Sanpro green gas and tested it. The M45 passed with a muzzle velocity of 32-34m/sec.

If the power drops too much, it may be a good idea to change the hop bucking to a stronger one.

[Precautions during installation]
1. Please prepare a BB speed measurement device.
2. To avoid injury, if a minor is performing the work, please have an adult supervise.
3. This product was created based on Tokyo Marui Government series 1911/M45, etc. Since the inner barrel is extremely short, it may hit the outer barrel during firing. Therefore, if the outer barrel has a folded-back tip, please customize it by filing it down.
4. Regarding Glocks, in tests with the G18C, the outer barrel always hit. However, by installing a DCI Guns outer barrel, full-auto firing was possible without any problems.
Please install it with a free and flexible approach.
