CowCow B01 Dynamic Blowback Housing for Hi-Capa - Silver

The CowCow B01 Dynamic Blowback Housing for Hi-Capa - Silver is precision CNC machined from aluminium 7075 for ultimate durability and quality.

Weighing only 18 grams, this blowback housing improves cycle and gas transmission. The special design of the piston head ensures that the O-ring is always in perfect condition. It minimises air leakage during blowback action and the different sizes of the included anti-oil O-ring fit commonly used nozzles on the market. It can effectively stop the slight wobbling during nozlle movement.

Includes 3 different sizes of 9.5mm*2mm, 9mm*1.9mm & 9mm*2mm (inner diameter * diameter) black O-Rings.
The B01 Blowback Housing is compatible with Tokyo Marui Hi-CAPA / 1911 Series Airsoft GBB Pistols.

The screw for the nozzle is loosened by default upon packaging. The user must tighten the screw before installation. Cowcow recommends using thread locker while doing so to prevent the screw from vibrating loose.
