Need Opinions for a New Bull-pup!!

25 Cricket with a power tune is what I would buy. Without stressing the reg or HS they are pushing the 34 grain over 920 = 63+ fpe. Georgia Airguns has a couple for sale.

I will take the Cricket mag/loading system over a Vulcan or Impact. With a little practice they are a easy use plus you will spend less time loading mags and more time shooting.
