POA/POI - Otter Creek Polonium

Published on May 18, 2024
Duration: 1:01

This video demonstrates the point of aim (POA) versus point of impact (POI) shift experienced when attaching an Otter Creek Polonium suppressor to a 5.56 firearm. The instructor conducts a brief test, firing shots without the suppressor to establish a baseline POA/POI, and then re-evaluates after attaching the suppressor to observe any changes in impact.

Quick Summary

Suppressors like the Otter Creek Polonium can cause a Point of Aim (POA) vs. Point of Impact (POI) shift due to altered barrel harmonics and gas dynamics. It is crucial to re-zero your optics after installing a suppressor to ensure accurate shooting.

Frequently Asked Questions

What is Point of Aim (POA) vs. Point of Impact (POI) shift with suppressors?

POA/POI shift refers to the change in where your bullets hit (POI) relative to where you were aiming (POA) after attaching a suppressor. This occurs because suppressors alter a firearm's harmonics and gas dynamics, affecting bullet trajectory.

Why does a suppressor cause POA/POI shift?

Suppressors can cause POI shift due to increased back pressure, altered barrel harmonics, and potential slight canting of the barrel. These factors influence the bullet's flight path, leading to a different impact point compared to unsuppressed fire.

What is the Otter Creek Polonium suppressor?

The Otter Creek Polonium is a suppressor specifically designed for the 5.56 NATO cartridge. It's intended to provide effective sound and flash reduction for firearms chambered in this common rifle caliber.

Should I re-zero my rifle after adding a suppressor?

Yes, it is highly recommended to re-zero your optics or confirm your zero after installing a suppressor. Suppressors can induce a POI shift, and re-zeroing ensures your aim accurately reflects your impact point for consistent accuracy.
