Structural Evolution. Performance Enhanced.
● One-piece CNC-machined HOP-UP chamber construction ensures exceptional structural rigidity, machining precision, and overall stability.
● Compatible with standard GBB buckings and designed to fit the first locking groove of standard inner barrels.
● Integrated bucking side alignment design ensures consistent bucking positioning, improving assembly accuracy and air seal stability.
● Dual-sided T-LOCK design supports both wide and narrow inner barrel locking grooves, providing greater compatibility and installation flexibility.
● Dual-side clamping structure precisely secures the inner barrel concentrically within the HOP-UP chamber, enhancing shooting consistency and accuracy.
● Proprietary screw design minimizes the risk of mounting hole deformation caused by repeated assembly and disassembly, while enhancing durability and simplifying maintenance.
● Dual-side elastic support design centers the HOP-UP chamber securely within the outer barrel/receiver, improving alignment precision and minimizing movement.
● The adjustment screw features an anti-slip treatment to resist loosening under prolonged vibration, ensuring reliable long-term stability.
● Upgraded TDC (Top Dead Center) HOP-UP adjustment system:
Delivers even and consistent downward pressure through a circular curved contact surface, providing more effective and stable backspin.
Features a stepless micro-adjustment mechanism, allowing finer and wider-range tuning for precise adjustment with both lightweight and heavyweight BBs.
Incorporates a spring-loaded adjustment ring to maintain constant tension, effectively preventing loosening and ensuring consistent HOP performance during extended use.
