AA CNC Aluminum Hop-up Unit for Tanaka M700 – Black

CNC Hop-Up Chamber for Tanaka M700 by Action Army
This precision aluminum hop-up chamber is designed for sniper rifles in the Tanaka Works M700 gas system. CNC machining from high-quality aluminum ensures excellent strength and airtight sealing. The chamber significantly improves performance consistency and allows for precise and fine-tuned hop-up pressure adjustment. With the redesigned pressure system and included Omega Nub roller, it is optimized for heavy sniper BBs up to 0.49 g. The chamber locking system is dimensioned for GBB / VSR type inner barrels. The internal layout provides optimal pressure around the hop-up bucking, achieving perfect sealing, maximum muzzle velocity, and reliable feeding with proper BB alignment before firing—a key factor in accuracy. Combined with a quality hop-up bucking and inner barrel, this chamber is an essential upgrade to improve accuracy and extend range.
