Yeah I've brought parts from Redbeck before, as to anything else that'd all be dependant on lift there etc, it's just nice to mooch a shop where possible as my area lacks them aside from Airsoft (although Airsoft may consider Air Guns in the future and local fishing shop has said they can get anything on request from SMK).
It also depends on how I am after doing the stairs and shooting, if things are screaming no point doing it if I won't enjoy it.
