If there's anyone thinking about buying this rifle I'll just let you know:
Other than buying a dedicated .22LR upper for your AR15 this is the BEST training rifle you can get. All controls are identical to a full size AR15. I bought one as a trainer for my Wife and for myself to save cash on ammo and it's a damn fine little rifle. Hell it even breaks down the same.
Werfin' nebels yo!
