New Bore Up (NBU) cylinder set from Systema with increased capacity of air. Set includes all necessary components of cylinder set which have mutually optimal dimensions and offer a perfect tightness. According to our many years of experience in the field of upgrading, with this set you can achieve the greatest performance increase over the real stiffness of spring. The shape and material of the quiet impact surfaces on the cylinder head and the piston head is made to minimise unwanted noise that is created by impact of piston to the cylinder head at the end of each shot. For optimal function is recommended by the manufacturer for springs M130 and above.

The entire set includes the following components:
• Polished stainless steel cylinder with vertical ribbing and a large internal capacity.
• Stainless steel cylinder head containing 2 pieces of rubber o-rings for a perfect tightness and better stabilization in the cylinder.
• Lightweight plastic nozzle with o-ring and a very precise shape, length and end outcome.
• Lightweight plastic piston head with o-ring and vacuum suction holes teardrop shape. Bearing on the piston head prevents undesirable twisting of spring.

Attention: Due to the different dimensions of NBU components it can not be combined with conventional parts of basic cylinder set. Sometimes this is possible only after correct adjustments.
