Kriss was never about the gun , only the mags. And yes, mec-tech isn't an AR (I know), but still a good carbine..Move the goalposts much?
Your original post said you had two carbines, a Kriss and a MechTech. Neither are even vaguely considered AR platforms.
Additionally, you saying you had issues with whatever brand of 10mm AR only reinforces my earlier point…10mm AR’s are unreliable.
