Balystik No-Drill HPA Valve GBB KJ WE VFC US

🔧 The no-drill HPA valve is designed for gas blowback (GBB) or GBBR magazines with a 5mm threaded input, such as KJ Works, WE, Stark Arms, and M&P9 models. It allows for a seamless transition to HPA without drilling or major modifications.

🛠️ This no-drill HPA valve ensures a secure and airtight fit using thread locker resin, allowing flexible depth installation depending on the brand. Always tighten until fully seated.

⚠️ For GBB mags with a rubberized baseplate, some modification may be required.

🚫 Do not use PTFE tape. The integrated resin system ensures a safe, leak-free connection.

🔌 Compatible only with US-type pressure couplers such as REDLINE, NINJA, VALKEN, Wolverine, or Balystik US lines. ❌ Not compatible with Marui magazines or EU-type HPA connectors.

👨‍🔧 Professional installation is recommended. Converting gas mags to compressed air can be hazardous if done incorrectly. Do not exceed the original gas pressure limit of 110 PSI, as this may cause serious injury or equipment damage.
