Apologies if already posted. I just noticed Volquartsen makes a Competition Bolt for the 15-22. Anyone used one yet? I am seriously considering upgrading my 15-22's for the cleaning and smoothness aspect. I have their Black Mamba pistol and the coating on that bolt is Amazing. Like glass. You just wipe the dirt off. What is interesting is it says it is also compatible with the 15-22 pistol but my pistol bolt is definitely not the same as the rifle.
