I tried a Spectre ...
On a 22lr, I doubt very much you can tell a difference between any of them just by ear. The action on a 10-22 is far louder than the gunshot on all of them.
I own an AAC "Pilot," but I've shot several others and stood near DOZENS of others being used at shooting ranges all over Georgia for the last 20 years.
They all sound about the same to me.
Even cheap ones, even home builds on a Form 1.
All I can say is that I wish I had purchased one that was rated for 22 Magnum or 17 magnum rimfire, because it's a bummer that mine is rated for Long Rifle only.
