[Big-out] Big-out Original Junior Detuned Barrel for Electric Guns 135JP1

Big-out Original Junior Detuned Barrel (for Electric Airsoft Guns)

By detuning your airsoft gun, even children can enjoy playing airsoft together!
Turn painful close-quarters combat in indoor and CQB fields into a fun game!

*This product is a custom part for advanced customizers.

This is a custom adjustment part intended to detune (detuning means lowering the power of the original product) electric airsoft guns for ages 18 and up to be compliant with ages 10 and up (within 0.135J) by simply replacing the inner barrel of airsoft guns with a Tokyo Marui electric gun compliant hop-up system (compliant means products with the same shape as copies, etc.).

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

※Please note that since this is a custom product, simply installing it does not guarantee within 0.135J.

(Manufacturer's data) Measured with 0.2g Finest BBs using a next-gen HK416, muzzle velocity of around 91m/sec. Replacing the barrel alone resulted in a measurement of around 34m/sec.
Overseas standard type M4 series, muzzle velocity around 90m/sec. Replacing the barrel alone resulted in around 32m/sec, and the flight was excellent.

If it's too low, a good method would be to replace the hop-up bucking with a stronger one.

【Precautions during installation】
1. Please prepare a BB speed measuring device.
2. To prevent injury, if a minor is performing the work, please have an adult supervise.
3. Tests have been conducted with various electric airsoft guns, and while the product has been commercialized with adjustments made primarily by replacing stock parts, adjustments may still be necessary.
4. For AK series, please create and install an inner and outer barrel. The same applies to P90/G3 series.
5. Since the 135JP1 has a total length of 70mm, we recommend Big-out's BMR or similar for inner barrel stabilization.
