Colt actually has a recall on some 6920's going on right now. S/N's at the link.
RecallFar as I can tell, those are all the new CR models. I personally wouldn't own one.
Mine are LE/LEO.
Dang, and some of us had high hopes for CZ..... I like my old Colt as well... Runs like a Timex.. As far as Rittenhouse is concerned. What kind of ammo was he using? Steel cased or some other cheap azzed military chidt? I know there is a separate thread on the use of the FA, but I've never had to use one. I only run my handloads though... I'm also thinking that he has tons of experience with his rifle not loading ammo in all the way, as he was so quick to know to bump that FA when it didn't go into battery... So it was either a gun fault or cheap azzed ammo...
