Unfortunately I "had" one a few months ago, ended up selling it so I could buy a S&W MP15-22. My COLT experienced multiple FTF's on standard long rifle bulk paks. After reading the instructions, I found it only the use of "High velocity" rounds (@$8 per 100), the manual also recommended that you use the supplied allen wrench and turn the spring adjustment in all the way until is stops. After doing this and using HV ammo (CCI or Rem Viper's), the rifle performed nicely with just a couple of FTF's.
I sold mine because it didn't quite live up to my expectations.

The trigger was very heavy and was in a "pot metal" housing making any adjustments impossible. The barrel is actually a tube held in-place inside the outer shell of the rifle, the flash hider is used to center the tube inside the shell (be sure you use the wrench to loosen the flashhider so you can separate the halves). There is no bolt hold back except for last shot fired (although you can reach up into the magwell and push up on the spring and activate it manually. The cute little bolt release latch on the left side is strictly for display and non-functioning. And lastly after separating the halves, cleaning of the non-removable bolt assembly is by spraying gun cleaner into the mechanism and letting it dry. Be careful of a little plastic lug on the lower half as it falls out during separation of the halves. Before taking it apart for cleaning search YouTube for "COLT M4-22 field stripping", there is a very good video on how this is done.
The Smith on the other hand, operates and has full function like the AR models. Bolt catch, trigger and bolt assembly all function like original model, I am very pleased with the rifle. Another good aspect is it is cheaper than the COLT.
