Crosman 600 finish?

[Shed tuner]

I've fitted an 18" barrel to mine and made an extended front tube and filler so I can bulk fill it with co2
when I get time I'm going to machine up a scope rail and fit a stock and forearm
the biggest criteria is that no permanent changes are made to it

Suggest you chrono it. When I fitted a longer barrel I found 12" put it over, so went to around 10" for a nice 5 FP and better accuracy / less noise. If you convert it to a carbine, I guess that's fine.

well aware of the better use of co2 when a longer barrel is fitted but thanks for the reminder
will only be fitted with a long barrel when a stock is fitted and tbh it will more than likely not get used and be kept in std pistol form
