About Shipping Inquire about this product
Product Description
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※
This product is exclusively for the new MARUZEN CA870 HOP. Please be sure to check the shape of the barrel of the CA870 you are replacing before purchasing.

The barrel shapes of the old and new HOPs are completely different. This product cannot be installed on the old HOP. Please refer to the reference photo for compatible genuine barrels.

This product has an outer diameter of 8mm around the HOP window and 8.55mm elsewhere (MARUZEN genuine barrels are 8mm). Some parts, such as the inner barrel spacer, may require modification during installation. In that case, you will need to enlarge the hole in the barrel spacer or modify it yourself.

※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.
