A very good friend of mine has a really nice 22 cal air rifle. I forget what brand it is, but it cost him around $450, and got very good online reviews on several of the air rifle forums, and it's served him well in keeping the rabbit population under control on his vegtable farm.
WELL......he dropped it a couple of weeks ago, and the optics on the (CHEEP!) scope got knocked out of alignment to the point that when I looked through it, instead of seeing a round circle of light, I saw an oval.
And it kind of rattled a bit when you shook it...
So, I gave him the scope that came from Marlin on my 336 (I replaced it with a Nikon scope), along with several sets of rings of various heights so he could get it mounted to his preference. I helped him sight it in, and all is well. The rifle is a real ass kicker for an air rifle, and will punch clean through one side of a galvanized trash can, and almost through the other side at 25 yards. Pretty impressive to my thinking!
HOWEVER....he keeps reading on the forums that you need to use a specially designed scope made specifically for air rifles to withstand the back-and-forth shock that comes from the piston slamming forward to compress the air, and then the recoil from the pellet going out the barrel.
I'd never heard of that before. Can anybody with air rifle experience shed some light here, or is it just an "Internet Myth"?
He's worried that that "expensive" scope I gave him will get damaged, and even though I don't want the scope back, I'd like some info to put his mind at ease.....
