Cow Cow 3L HopUp Chamber for TM HI-Capa

Upgrade your Tokyo Marui HI-Capa or 1911-series airsoft pistol with the Cow Cow 3L HopUp Chamber. CNC-machined from 7075 aluminum, this lightweight, high-durability chamber is designed for serious shooters who want steadier accuracy and easier tuning.

• Material & Craft: 7075 aluminum, CNC machined for precise fit, combined with a lightweight profile that withstands regular field use.
• 3L Design: A three-layer design that reinforces the lower chamber area to boost accuracy and consistency without adding bulk.
• Double Lock System: Ensures the chamber remains securely mounted to the frame while the hop-up wheel locking point prevents preset position drift.
• Detachable Chamber Pin: Included pin supports guide rod alignment, especially beneficial for 1911-based builds.
• Compatibility: Specifically designed for Tokyo Marui 1911 and Hi-Capa 4.3/5.1 pistols, compatible with both plastic and metal slides.
• Installation Notes: Requires a small amount of screw glue during installation; apply a drop and let it dry overnight to protect threads. Intermediate gunsmith knowledge is recommended for proper fitting; consult a gunsmith if unsure.

This upgrade helps stabilize the chamber, reduces movement during fire, and supports precise hop-up tuning. Expect improved feed consistency and more reliable accuracy across shots, especially when dialing in hop settings. The combination of the 3L structure and secure locking mechanisms makes it a practical, long-lasting enhancement for competitive shooters or dedicated hobbyists seeking repeatable performance.
