Keltec showed off the RDB Tactical or whatever it was called athe SHOT this year and one of the features was an adjustable stock that could add I think an inch of LOP. They said it will be available as an aftermarket upgrade part from Keltec later this year, so I may hold out for that. Honestly it shoots great as is, having a little more LOP is more of a want, but not a necessity for me.
