Archwick Pinnacle Hop Up Unit for Mk13 series/Tokyo Marui VSR-10.
This custom hop-up chamber kit is compatible with the Tokyo Marui VSR-10 G-SPEC and is compatible with the Mk13 Mod7/Mk13C rifle series.
It is made from CNC-machined aluminum, and the inner barrel and hop-up pad are inserted and fixed from the muzzle side, ensuring excellent airtightness.
This chamber can be used with all inner barrels with outer diameters between Φ8.55 and Φ8.5 that use Tokyo Marui VSR-10/Tokyo Marui GBB compatible hop-up packings.
Regardless of whether the barrel has a bridge or not, or whether it has a groove for fixing, the sleeve can be placed over it and fixed with a set screw. The package includes one genuine ARCHWICK long-type hop-up pad (made of silicone rubber) for barrels without a bridge.
The hop adjustment screw is designed to be accessible from both the magazine side and the top of the chamber, but access from above requires drilling a hole in the outer barrel.
Another major feature is that the lever and push part are separate. Two push parts are included: one for a Φ2.5xL6 round bar, and one for a round long hook with a total length of approximately 6.6 mm, so you can freely choose the part that best suits the shape of your hop-up gasket.
When you press the lever, this pressing part moves up and down vertically, so you can press the gasket evenly. Also, since this part is quite large, you can create any shape you like using cutting or a 3D printer.
This is a chamber with great potential and a high degree of freedom to play with.
