We do. I said please dont play with them. Kinda thought it would be obvious. You play/tinker it will cost money and in the case of the barrel probably quite a bit. I can only let people know not to play and tinker. It's up to them. At the moment with limited staff due to covid 19 it is much more difficult to get things done let alone sort issues with rifles that shouldn't be there in the first place if they had just been left well alone. Slightly different with the fx rifles as there are far too many youtube videos from quite frankly idiots that are all of a sudden air rifle engineers/designers that think they are being helpful. The issue is that the average joe bloggs on the street isn't an engineer and cocks it up. I am not sure what you work on but i somehow don't think there are that many youtube videos on how to take your equipment apart and "tune it" within a micron of it's life potentially making it illegal or plain dangerous or both.
