When I found from the 2017 SHOT Show that my favorite High Power Springer “Do-All” scope had been discontinued, I was almost depressed. However, there was a new scope that seemed to have some potential – the Sightron SIH412X40FTMOA.
I’m a great fan of the Diana 54, but the problem with it is that, at full power, the gun will serve the scope between 15,000 and 30,000 G of force (in about 0.1 Milliseconds) upon every trigger pull. Yes the shooter does not feel anything, but the scope bears the brunt of the “free-recoil” of the sled-equipped action.
The Diana 54’s sled system decouples the action from everything else during the firing cycle. Only the action’s and the scope’s weight are there to resist the forward recoil when the piston stops at the end of the compression stroke.
So, there are few guns that can put out more forward recoil than the Diana 54. That is why they are known “scope eaters”, especially, in the full powered versions.
The challenge then was to find a mechanically-strong scope with good optics and a useful reticle (multiple aiming points), at a reasonable price. And one that the 54 would not break…
Enter the Sightron SIH412X40FTMOA. This scope is a new SI series, Field Target line, Hunter oriented 4-12X40 AO model.
The Sightron SIH412X40FTMOA has a 1 Inch tube and Adjustable Objective. Focus is from about 8 Yards to infinity at 12X, the reticle is the new MOA-20, that presents a useful number of divisions to estimate the range, as well as to place accurately the shot.
Weighing in at just over a pound, the Sightron SIH412X40FTMOA is no lightweight: but neither is it a heavyweight. In general-purpose airguns, you do NOT want a top-heavy rig, as it throws the balance off and makes the “artillery hold” that …read more
