Got one for $225 with 2 mags at a show sunday, just got to shoot it today. Had a few feed problems and a few light primer hits. Once sighted in I was able to hit my “gong” (more of a CLANK) 5in steel plate from 30yds 7 out of 10 rounds. They claim some fancy “chiappalloy” metal construction, seems like cast aluminum to me. Its basically a metal airsoft gun converted into a .22.
Currently Im happy with my purchase, I found a few webpages with info on it and made a few modifications to the extractor. As long as the feed and light primer hits stay low enough that I can blame most of them on my cheap ammo everything will be fine. At 9yds is so accurate I hear my inner Hickok45 chucking when I shoot pop cans and my spinning target from walmart. I actually sold off my Ceiner .22 slide off to buy this and If it does not break or fail I will consider it a win.
