How to Choose the Right Scope for This Pistol
Choosing the right optic for an M110-style rifle requires understanding how you intend to shoot. Since this platform is typically used for precision semi-auto shooting, your scope must support consistent accuracy across varying distances.
First, magnification is critical. I recommend a minimum of 4-16x for general target shooting, but if you regularly shoot beyond 600 yards, stepping up to 5-25x gives you better target identification and precision.
Second, focal plane matters. I strongly prefer first focal plane (FFP) scopes for this rifle. Because the reticle scales with magnification, your holdovers remain accurate at any zoom level. This is especially useful during dynamic shooting where you may not always be at max magnification.
Third, turret quality is non-negotiable. The ability to dial precise adjustments and return to zero is essential. I always perform a box test when evaluating scopes, and budget optics that pass this test are worth considering.
Fourth, glass clarity affects your ability to spot impacts and read mirage. While budget scopes won’t match premium glass, some models offer surprisingly good clarity, especially in the center image.
Fifth, durability is key. Semi-auto rifles like the M110 produce consistent recoil impulses, so your optic must maintain zero over hundreds of rounds.
Finally, consider weight. Heavier scopes offer better features but can make your rifle front-heavy. Balance is important for extended shooting sessions.
