Whether an LPR is adjustable or not (if it has one) depends on the marker. Some markers have non-adjustable LPRs due to their design or modifications. The vast majority of current poppit-types, spoolers, and autocockers have adjustable LPRs.
Certain settings are needed to achieve an LPR's (and ultimately the marker's) best performance. The range of adjustment, proper setting, and how to set it up may depend on the marker, the brand and/or type of LPR, the type of gas you use, and whatever modifications/aftermarket parts are being used.
Most of it is straight-forward though. Do some research if you are wanting particulars about operating pressure w/other aftermarket parts.
