Edgun R5M ping...

[Haganaga]

What a difference two months make. I ordered a Huma from Edgun west. I broke out the chrony and started adjusting. Maxed out the hammer spring tension so had to go back in the tube. Read something on here that 34 grainers were using Humas between 125-130bar. What the heck, 130 it is. Shooting with the stock UNSCREWED I was able to quickly up the tension for 905ish fps. Zero distance was pellet on pellet and later hunting was spot on. 


Now for the unexpected update No Ping!!! I do remember it during my tuning but wasn’t paying enough attention to it rather the chrony numbers to know exactly when it vanished. But I’m damn glad it’s gone!

Yeah, the ping on my R5M went away after around 1000 pellets through it using the factory regulator. No adjustments were made to the regulator. Only the hammer spring tension. The only sound I hear now is described as a "tink".

Yes, that hammer strike. But I am so psyched that big ping went away. Maybe if I just shot it more it might’ve went away on it’s own. But I am glad it was sooner rather than later.

I know it’s an old thread but I had a long battle with the ping on my R5m as well. Having scoured the forums I figured out it’s a harmonic tune thing. At a certain amount of hammer sprint to reg pressure it goes away.
