I have 350 rounds through a Mk 2 LLV right now with no cleaning and minimal lubing with zero malfunctions so far but I wouldn't use it for self defense its definitely not capable of stopping a crackhead @ 7 yards

Choice of ammo is also a big factor. All of the cheap shit like remington, Winchester, federal burn dirty as hell and will gum up a 10/22 real quick. Fiocchi and CCIs higher end stuff is a better choice for .22 imo. I've actually had a remington case shear and blow out the extractor on my 15-22, not fun times.
