OK so I've been looking around, People (Like SBNC and the Trudge on) have more than one flywheel, I like the idea but I was wondering. Has anyone ever put them into a barrel extension so that you can take the extra flywheels off at will or if you don't want to you can have even more flywheel power.
This could also be used with springers as well, not sure how well it'd work but the idea's there someone smarter than me has to do the research.
