PDI Bore Up Premier Cylinder Set VC for TM VSR 10/JG BAR 10

Description:
The PDI Bore Up Premier Set VC for Marui VSR10 / Bar 10 is the ultimate upgrade kit for your sniper rifle. Bore up kits are designed to dramatically increase your gun's velocity in conjunction with a stiff spring by allowing more air to power the BB. PDI is considered to be the premier manufacturer of Tokyo Marui Upgrade parts, and they've lived up to their reputation with this kit. The cylinder is bored smooth from stainless steel for a stronger and smoother surface resulting in an uninterrupted air flow all the way through the nozzle. The cylinder head is machined extremely well and has one o-ring at its base, one o-ring under the threads that keep it secured to the cylinder, and one o-ring on the end of the nozzle for an air tight seal. The spring guide is made with equal care, the machining is exquisite. The piston is made of a lightweight aluminum. The lighter the piston is the faster it can accelerate when released from the sear, ultimately resulting in higher BB velocity. Also, the head of the piston is ported and features two o-rings to ensure all of the energy from the piston is used to propel the BB. Every single part of this kit was carefully designed and machined to achieve the best possible performance from your spring. No body does Tokyo Marui Upgrades like PDI, and they've just raised the bar with this amazing VSR-10 kit.
