With TM VSR's the o-ring that comes with the Neo Piston/Zero Trigger is known to provide a less-than-perfect air seal. The stock o-ring that comes with the VSR does a much better job. The o-rings that come with the clones are a hit-and-miss bunch though. The o-rings that come with an HFC USR-11, for example, are worse than the o-ring that comes with the Zero Trigger.
To make things really simple: To obtain optimum compression you will need to replace the o-ring.
