LPVO 50 Yard Zero for MK18

Published on October 1, 2021
Duration: 4:18

This video demonstrates how to perform a 50-yard zero on an MK18 rifle equipped with a Mark 6 front focal plane LPVO. The instructor emphasizes the importance of ammunition velocity (2600 feet per second for SS109 62 grain) and shows the ballistic performance at 50, 100, and 200 yards. The results indicate that a 50-yard zero is effective for an area of operation up to 200 yards with this setup.

Quick Summary

A 50-yard zero on a 10.3-inch barrel MK18 using SS109 62 grain ammunition (approx. 2600 fps) is effective for engagements up to 200 yards. At 100 yards, expect groups around 1.25-1.375 inches. Beyond 200 yards, shots will fall significantly low.

Frequently Asked Questions

What is the effective range of a 50-yard zero on an MK18 with an LPVO?

With a 50-yard zero on a 10.3-inch barrel MK18 using SS109 62 grain ammunition, the effective range for accurate engagements is generally considered to be up to 200 yards. Beyond this distance, the point of impact will drop significantly.

What ammunition velocity is recommended for this MK18 zeroing procedure?

The video specifies using SS109 62 grain ammunition that shoots at approximately 2600 feet per second. This velocity is crucial for understanding the ballistic trajectory and predicting impact points at various distances.

How does barrel length affect projectile velocity for an MK18?

A 16-inch barrel can achieve approximately 2900 feet per second with the same ammunition, while a 10.3-inch barrel on an MK18 will yield around 2600 feet per second. This difference of 300 fps highlights the impact of barrel length on muzzle velocity.

What kind of accuracy can be expected at 100 yards with a 50-yard zero on an MK18?

When zeroed at 50 yards, an MK18 with a 10.3-inch barrel and SS109 ammunition can achieve groups of about 1.25 to 1.375 inches at 100 yards, demonstrating good accuracy for this setup.
