This precision-engineered aluminum hop-up chamber is designed for sniper rifles based on the Tokyo Marui VSR-10 system. The CNC machining from high-quality aluminum ensures excellent strength and a tight seal. The chamber significantly improves consistency and allows for more precise hop-up pressure adjustment. Thanks to the refined pressure system, it supports heavy sniper BBs up to 0.49 g. The chamber locking lugs are designed for use with GBB / VSR-type inner barrels. The internal layout delivers optimal pressure around the hop-up bucking, resulting in a perfect seal and maximum muzzle velocity, along with reliable feeding and precise BB centering before each shot, which greatly affects accuracy. Paired with a good bucking and inner barrel, this chamber is a fundamental upgrade for improved accuracy and extended range.
