Used to struggle to make above £135, get listed for more and sit and sit until someone accepted an offer .......
Plus Mod, plus scope / mounts
I reckon sell rifle, mod, scope, mounts separately if you are looking for best return _ I'd be amazed if you got 200 for the 'combo' even now though will easily get that if itemised.
I saw a Pro s moderator go for 40, (though I wouldn't pay that for one, if I wanted one)
