Where do you find the 60gr Aguila super sniper subsonics?
Sweet project gun BTW!
If it's just the ringing of the barrel shroud that's bugging you then all you need is something to dampen the vibrations. Try putting two or three good-size rubber bands around it, not too tightly and especially in the middle and end, and I'll bet your ringing goes away.
Bam, just saved you $350+.
Barrel length has little to do with accuracy.
I have two mist 22 Gemtech integrally suppressed barrels
They are a bit ammo particular, nothing odd about that.
Not surprising that it shoots 1/2 to 3/4 inch at 50 yards all day long with the orange box Gemtech stuff (made by CCI BTW, the 5,000 rounds having arrives in a CCI case)
I'm searching for one of these rifles!
SGA on I45 in Spring had (at least one that I shot) Gemtech integrally suppressed .22 a couple weeks ago.
