fitting the Ratworks quick fill adapter to the ANSCHUTZ 9015 ONE RIFLE
after keep removing the air cylinder every time to refill with air, apart from keep unscrewing the cylinder from the rifle, then undoing the dive bottle hose to fit the Anschutz adapter to fill up and put back in the rifle, I started to think of maybe long term damage to the thread and the rifle, so decide to purchase from Ratworks the quick fill adapter.
here's the way I done mine, not saying it is the correct way, or you should do it yourself, its just the way I done mine without any problems at all, no damage or no scratches on the cylinder
the fitting of the adapter is very easy to do and took less than 30 minutes to do,
as for the product itself it truly is a nice bit of kit, well made and well engineered, I wouldn't hesitate in buying one, if only to save any damage to the cylinder after long term use, plus also its a lot quicker and easier to refill

really sorry for the bad audio and video content, I'm not a video editor or sound engineer, I'm more hands on and get the job done, hope some of you will find this useful thanks for looking
