I paid £30 for mine as a wall hanger thinking it was an aeg untill I opened it up ! Spent a couple of hundred on spares and mags and now I have a fully functioning GBB L85 , it's great for gaming too and of course uses the same mags as my L119's
I replaced the trigger box , bolt including nozzle and a few other odds and ends. It had been converted to some sort of laser based training platform so the trigger box had been butchered.
