Got it to the range this morning, was pleasantly surprised at how well it shot! Sure, loading every round and having to manually cock it (STS) is a pain; but it's a accurate shooter! Plus, shooting three bucks of .22LR is a lot easier on the wallet than $23 worth of 7.62x39 (three mags).
Keystone sells a scope mount for it, I might considering putting a cheap TASCO or BSA one on it.
I also have some .22 CB rounds that should work in it, they are low muzzle velocity (between 350-700 ft/s, about the same as a pellet gun) but the actual bullet is significantly heavier than a typical airgun pellet and therefore carries more energy, so they are more lethal!
They also have almost no report, so I could actually use 'em in the back yard without anyone knowing! It'd be a good way to get rid of that fucking cat that keeps pissing in our hedge!
Cheers! M2
