I've not had a Ruger semi .22 for a few years now so when the opportunity popped up to take a MKII in trade I jumped in. I had a set of grips I'd been wanting to use so it had to be a MKII. I ordered up the full competition kit from Volquartsen and reacquainted myself with the full teardown and rebuild which took all three hands but in the end came out fine. Shoots like a dream and scratched the itch just fine.
