Cylinder set, Bore-Up, AK, SHS

Bore-Up set for AK war from SHS with increased capacity of air. Set includes precision made aluminum cylinder with ribs, a metal cylinder head with a double tightness, a tight nozzle with a metal o-ring (length 19.7 mm) and Lightweight piston head with bores and bearing. The impact surface of the cylinder head and the piston head is technically solved to minimize unwanted noise that creates shock of the piston after the shot. Unbeatable price/performance ratio.

Attention: Due to the different dimensions of parts not NBU/Bore-Up combined with conventional basic components of air conditioning. Sometimes this is possible only after appropriate modifications.
