I ran mine at a charity sporting clays event a few weeks ago. Was great to see all the fudds shudder and gasp at the nasty black gun.
The irons weren't very good for clays (which should have been pretty obvious), so I just took them off and sighted down the slot in the top rail (I've since put a little red dot on it - I'd like to try it with clays again soon).
Gun ran 100% during the first half of the day, but I started getting some stovepipes towards the end of the day when the gun started getting dirty... BUT I was running the heavy load gas ring with target ammo (because it seemed to work fine with target ammo when I took it out the first time and I thought I might just keep the heavy ring in it all the time so I could switch ammo and not have to worry about it). Stupid me forgot the little box with the chokes (& the light load gas ring) at home so I couldn't change it out when it started acting up.
I'll be running it in a 2-gun match this weekend... This time with the light load gas ring in... Hoping it will be as reliable as my AR.
