I have a couple of the bargain refurbs. Basically the Hatsan Edge/Striker powerplant except "modernized" with a lot more plastic around the barrel/muzzle and in the trigger pack. I'm skeptical about all the "new" plastic regarding long term reliability. So far my Airtact rifles shoot as well as any other Striker/Edge rifle I own. Aesthetically I prefer the Striker format followed by the Edge. I think the Airtact is the ugly duckling of the series but handling and performance is fine... so far.IMO a $40-$50 Airtact refurb is a good project rifle.
