These custom pistons are a great addition to your upgraded VSR Sniper Rifle.  If you need increased performance and want to use a larger spring, then these were made for you.

 

The Red Piston is a high pressure piston with a silent shaft.  This is the choice for most players, boasting improved performace and use with springs up to 150.  Will not work with Zero Point Trigger System.

 

The Orange Piston is also a high pressure piston designed to be used with the Zero Point Trigger System (only).  This is the choice for only those players who want to push the limits of possibility.  This piston is designed for use with the excessively powerful 170-190 springs.  Caution:  Use of 190 springs may cause damage to even upgraded guns.  Sears can be broken or wore down quickly with these springs.
