I bought the 580 for my impact and used the 480 on the L2 also i did modified the lower tube and install it instead of the upper tube will have more room for the grip
The tube swap is awesome. This should be put on the 160 page Leshiy 2 thread. I would have done that first rather than buy the 350cc . I know with the .25 and bigger calibers the extra volume sure would be handy. Maybe EdgunWest has the factory tube end or can order them in. I like the OEM length of pull so I’ll leave mine as is.
