Changing AirArms “t-bar” fill port to a Foster fill port

I did at one time. But that was back when they were using the much older, much larger fitting.

Switched to Lane Quick Fill probe kits on my older S4/5xxs. On my newer factory regulated S5xxs I continue to prefer the Banjo fitting.

I mostly shoot tethered and the Quick fill and Banjo connect the hose at a right angle to the gun. Much more convenient than sticking out straight or using a right angle elbow.

I switched my S300 and S400 from the OLD Air Arms fitting (pre T-Bar) to the foster fitting. No complaints. Worked well. Used the Best Fittings kit.

If the T-Bar REALLY bothers you (I like it - I think it's safer and more secure and faster w/ gloves, etc.), I wouldn't hesitate. Just do it safely. There's a bleed screw right in on the valve body on the S510 that drains all the air from the cylinder in about 60 seconds. Great feature that makes it easy to do things like this.

If you need help or have questions, send me a PM. I have had S510's apart so many times I could do it blindfolded.

Thanks, the part has left England and I should have it soon.
