Thanks, the part has left England and I should have it soon.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.
Okay thank you. That clarifies it wellit is the volume of the air pocket that has went through the regulator and is waiting for the valve to open to push the pellet out the barrel , and when the pressure drops in that given space from firing a shot the regulator opens and replenishes that pocket of air with "hopefully the same pressure " each time you take a shot ! too much plenum and your reg may not cycle consistently per shot , not enough plenum and a lack of power ,
