T-N.T. GHK-AK Series GBBR Full Hop-Up Retrofit Kit V2 ( S+ Inner Barrel )

The T-N.T. GHK-AK Series GBBR Full Hop-Up Retrofit Kit was especially developed to replace and upgrade the entire GHK AK HOP-UP structure. With the ongoing demand for quality upgrade parts for GHK AK GBB, T-N.T. STUDIO has developed this Retrofit Kit that includes all necessary parts, including a T-HOP bucking and HOP-UP chamber for enhanced performance and durability.

T-N.T. GHK-AK Series GBBR Full Hop-Up Retrofit Kit Features

• HOP-UP Chamber: formed integrally with aluminum CNC, making it strong and durable for long-lasting use.
• HOP-UP bucking: specifically developed for GHK AK series, featuring an exclusive T-HOP design for better accuracy and consistency.
• The pressure block is vertical and utilizes a trailing edge cover design. When adjusting HOP-UP, the pressure block will not incline, ensuring stable hop-up adjustment.
• An elastic O-ring is added to the rear of the HOP-UP chamber. This ensures close integration with the outer barrel, preventing the chamber from sliding and the adjust ring from being too tight, which could otherwise affect HOP-UP adjustments.
• BB loading position is improved for better precision, contributing to effective performance improvements during use.
• Improves the original “AEG specifications rubber” to “GBB specifications rubber,” which effectively resolves BB feeding issues and the problem of the bucking’s lip folding inwards, maintaining good airtightness.
