I have a lower thats been waiting on an upper for a few months now. I looked at the Del-Ton flattop uppers Marks Armory had in the vendor section and was decided on that. I started to surf the site and came accross the Chiappa .22 upper for $325 with mag. It is imported from ATI, same people who import the GSG-5. It takes black dog mags, which my sig 522 takes as well. Called this morning and they had gotten them in yesterday so my coworker and I ordered 2 of them. I dont need a .223 upper (now at least), and I already shoot .22 everyday just about so I went for it. Anybody else on her own one? How do you like them? I read a review on it last night and seems like a quality upper thats not too picky on ammo like spikes. Thanks, Zac.
