I really like it, and yeah, you were close! It's a 32mm non-illuminated scope with a 3x-9x variable zoom. And it is in fact meant for .22LR - I picked it up brand new for a measly 250 PLN (~$60)

Granted, I rarely, if ever, use the higher zooms, because neither my MP5 or my cheap sniper rifle are accurate enough to make use of that kind of magnification.

And that prism sight looks real nice! I don't mind having a basic scope, since I've gotten quite decent at hip firing at close range, so I'd rather have the added power a scope like that provides.

And since you've shared your build, I'll share mine, in my dingy old garage back when I was cleaning it.

That one's without the foregrip and the laser module attached. It's quite literally a poor man's G3, but hey, as long as it works.

EDIT: By the way, judging by the positions and looks of all the pins and screws and some other parts, I assume that's also a CYMA?
