Airgun scopes..........the truth
Here is a quote from Straight Shooters Airguns:
Ultimately, there are only two features that make an airgun scope different than a firearm scope. An adjustable objective and optics that are anchored to handle the two way recoil of a spring airgun. Let's look a little closer at these features.
An adjustable objective is a feature that allows the shooter to "focus" for any distance from a very close distance s0 (sic) yards or meters to infinity. Most firearm scopes are parallax set for100 yards or more to accommodate the long distance shooting requirements of a hunting firearm. Airgun scopes, however, must allow the shooter to adjust the parallax to accommodate for shorter airgun distances. This feature is necessary to achieve the maximum accuracy in an airgun.
Anchored optics are optics that are anchored front and back to handle the forward and backward recoil caused by the mainspring's movement. Recoil in a spring airgun is different than recoil in a firearm in the sense that it isn't only the amount of recoil that matters, but the direction of the recoil as well. Mainsprings cause an airgun to recoil backward and forward while firearms only recoil in a backward direction. It is this two-direction recoil that can cause damage to non-airgun rated scopes.
Scopes designed for firearms have optics anchored to handle the backward movement of the recoil. Airgun scopes require that optics be anchored to handle the two-way recoil generated by the mainspring. But there is a catch to this feature so check our recoil ratings very carefully. Even though a manufacturer may rate a scope for airguns, it may not handle all spring airguns.
I don't know why some folks want to get on a band wagon about this. I have actually seen an airgun break the glass in a scope. The bidirectional recoil will shred a firearm scope. I have put very inexpensive airgun scopes on 30. 06 rifles that work just fine. By the way, if you are wondering about my experience with this I have MANY airguns.....MANY firearms........and MANY airgun scopes and firearms scopes. What caliber airguns you say? How about a .458 airgun that will shoot a 450 grain 45/70 bullet at 700 feet per second. My suggestion of these scopes is based on my understanding that Hi Point folks want the best possible value in guns and accessories. The Tasco Golden Antler scope is one of many airgun scopes that are actually able to deliver that value. The AO (adjustable objective) makes the scope much better than a simple non AO firearms scope. Don't you want the crosshairs and the image to be clear from 10 yards to infinity? I do. But then, what do I know?..........grin
