[PDI] HOPUP Chamber Ver.2 / Tokyo Marui VSR-10

Introducing the second edition, which maximizes versatility!

The second version of the popular PDI VSR-10 Hop-Up chamber is now available. A unique feature of this model is that it can now be used with the stock cylinder head. Previously, a dedicated cylinder head was required, but this has been redesigned to allow for versatility. While it no longer has the dedicated design of Ver. 1, compatibility is reduced, but the "ease" of being able to replace just one chamber and the "double stopper" that is even more resistant to bullet spillage make it a fitting Ver. 2. Whether you're new to the product or already own one, we highly recommend giving it a try.

The one-piece chamber with improved airtightness ensures stable flow rate and volume!
The difference is obvious when compared to the split-type genuine chamber. Compared to the split-type genuine chamber, which leaves concerns about air loss, the PDI chamber is machined from a round aluminum alloy bar and has a one-piece design that eliminates the air loss issue.

Made of POM, it won't damage the bullets! Prevents bullet spills!
Equipped with a double stopper to prevent bullets from spilling out to the rear. BB bullets fed from the magazine are tensioned upward. By pressing down on the left and right, it is possible to hold the bullets in place.

Double bars allow for fine-tuning of trajectory! Left and right adjustment bars improve straightness
Equipped with two hop-up adjustment bars, it allows for precise hop-up adjustment. To adjust, simply remove the magazine and turn the hex wrench. Turning the screw moves the bar up and down to change the hop-up strength. If you use the separately sold PDI W-Hold Chamber, the protrusions inside the packing correspond to each of the left and right adjustment bars, allowing for even more precise settings.

[About anodized aluminum products]
*During the anodizing process, unevenness or marks of a few millimeters may remain where the product is fixed.
*Since the screw part is inspected after the anodizing process, some of the anodizing on the screw part may peel off, resulting in silver areas, but if there is no problem with the functionality, we will treat it as a normal product.
*We have confirmed that the product can be used without any functional impact, so we do not accept returns or exchanges for cosmetic reasons.


※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.
