Resurrected by popular request, we are bringing back the original (now discontinued) SYSTEMA PTW Cylinders with aluminum cylinder walls! They share the same internal designs as all PTW cylinders, same durable material, and same high-quality CNC production. Except they are lighter, and custom-built just for us - and by carefully selecting our partner factory, we were able to pass on the savings to you!

In fact, we are so confident with their reliability, all ZShot Customs Cylinders come with a 2-Year No-Fault Warranty. So you can buy with confidence!

ALWAYS CONFIRM  VIA ACTUAL CHRONO READING BEFORE USING YOUR NEW CYLINDER!!  Like all spring-powered pneumatic components (including the original SYSTEMA PTWs), the main spring will break-in after about 500-1000 shots and settle into it's final velocity.  Each gun's output will vary (occasionally vastly) based on components used.  For example tight-bore barrels usually yield higher velocitites, where wide-bore barrels typically yield lower velocities.  Similarly, DSG setup will yield significantly lower velocitieis.  The above chat is for reference only and shows internal testing results under controlled environment inside our laboratory.   Always verify your own gun's output before use!

BREAK-IN NOTES:  To extend service interval, we have selected a more durable inner piston head o-ring (which pulls the nozzle) for our cylinders.  These much tougher o-rings may require mild break-in to function properly.  All new cylinders should be dry-fired ~50-100 times to help the o-ring seat against the nozzle.  (Don't worry, unlike regular AEGs, dry-firing your American PTW will have zero negative impacts due to the strength of Real Steel receivers.)  The above procedure is optional; most cylinders will not exhibit any issues at all, and even if break-in is required, at worst you lose a little bit of accuracy (due to muzzle velocity variations) and occasional BB chop if you skipped the break-in procedure. It will self-heal very quickly.
