AA CNC Aluminum Hop-up Unit for VSR-10, Damping Type – Grey

CNC Hop-Up Chamber Dampling Type with Slider for VSR-10 by Action Army
This precision aluminum hop-up chamber is designed for sniper rifles based on the Tokyo Marui VSR-10 system. CNC machining from high-quality aluminum ensures strong structure and great air seal. The chamber greatly improves consistency and performance while keeping the original hop-up adjustment via slider on the outer barrel—but without the original plastic parts, now replaced by a screw to control lever slack. The system is sturdier, more reliable, and yet easy to adjust like the original chamber. The mounting locks are tailored for use with GBB / VSR type inner barrels. Internal chamber design provides even pressure distribution around the bucking, resulting in perfect seal of the assembly, higher muzzle velocity, and reliable BB feeding with centered alignment before each shot—a major factor for tight grouping. Combined with a high-quality bucking and inner barrel, this chamber is a core upgrade part for boosting accuracy and range.
