[PDI] 6.15 Inner Barrel 187mm / PDI Patriot2

This is the loosest PDI barrel at 6.15mm. It improves straightness but reduces initial velocity, so performance may be reduced with a standard spring. Ideal for special settings such as flow rate tuning.

*Increased initial velocity and increased distance are not proportional.
*The above performance comparison is based on the Tokyo Marui standard electric gun M4A1.
*Please be careful when combining spring rates. Be sure to calculate and frequently measure bullet speeds to ensure you do not exceed the legal output.
*Although we use non-magnetic austenitic materials, they may become magnetic during the manufacturing process.

※please note※
If you have customized your airsoft gun or replaced parts, be sure to measure the bullet speed using a bullet speed meter to ensure it is within the legal limit (possession of bullets over 0.98 J is prohibited). Also, be careful not to exceed the legal limit during the work.
