Frequently Asked Questions

What is the best way to sight in a reflex sight quickly?

The most efficient method is the reticle-to-impact technique. After firing a shot, keep the firearm perfectly still on the original aiming point and adjust the sight's reticle to physically align with the bullet's impact hole. This significantly speeds up the zeroing process.

What tools are needed to sight in a reflex sight?

You will typically need the reflex sight itself, the firearm it's mounted on, and a flathead screwdriver for making windage and elevation adjustments. A stable shooting rest or bench is also crucial for accuracy.

What is a common zero distance for a 9mm carbine?

For a 9mm carbine like the Sig Sauer MPX, a zero distance of 30 yards is often recommended. However, the optimal zero distance can vary based on the specific firearm, ammunition, and intended use, with 100 yards being more common for other rifle types.

How long does it typically take to sight in a reflex sight?

With a stable shooting rest and using efficient techniques like reticle-to-impact, sighting in a reflex sight should only take approximately 10-15 minutes. This includes initial adjustments and fine-tuning for accuracy.
