What kind of accuracy and consistency are you getting? Chrony numbers? Scope you’re using? Power?
Pros: Interesting technology, lets you tune power level. Easier to disassemble than a springer, because you don't have to fight the spring. Very well made. Can deliver enough power to take advantage of .25 pellets and slugs, which adds to the interest factor.
Cons: It's heavy (over 9 lbs). It's expensive. I have not sorted out the accuracy issues. Mine came with significant barrel droop. You need to be fairly stout to cock it at the higher power levels. Maybe wear hearing protection.
Max power seems to be highly dependent on the piston seal. With the stock seal it's about 22 fpe. With the Vortek vacuseal, I got about 32 fpe.
It's my favorite gun at this time, although that may change later.
