Any experience with the SIG 556xi carbine?

Several years ago I was able to buy four 556 Classics for issue as patrol carbines. I was the chief FTO at the outfit ad saw then run with anything and everything I could buy cheap in bulk, including Tula. They were superb rifles and not one suffered a fail-to-feed or fail-to-eject in four years. They are roughly 2MOA guns with anything you throw at them, maybe half that with stuff they like. Ours really liked Independence 55 or any 62 grain.

The bolt its a direct knock-off of the AK and the piston system is adjustable and if anything, an improvement on it. Trigger is two stage and adjustable tp some degree. Due to the application, I never messed with them. It was plenty shootable as-is. I have no experience with the XI other than nearly dropping the shekels for one in 7.63x39. Found a WASR to build instead, been real happy with that.
