Yet another PCP (pre-charged pneumatic) came across the doorway today, vying for supremacy as my favorite with the previously described custom FX Tarantula. A very nice used DayState Harrier, also in .22 cal., became mine after a little wheeling and dealing with a shooting buddy. It's internal valving has been tweaked a bit, yielding a bit more ft.-lbs. of energy at the cost fewer shots per fill off of the ol' scuba tank or FX pump, whichever is closest and most convenient.
Nice factory walnut stock, a Simmons ProAir 4-12xAO atop it, and like the FX it too sports professionally installed sling swivel studs. Killed several squirrels ("tree rats") with it after an initial sight-in, and I think I'm in love!
