This video demonstrates the common phenomenon of point of impact (POI) shift when attaching a suppressor to a rifle. The instructor emphasizes that this shift is almost always present and can be unpredictable, often resulting in a 2-inch movement up, down, left, or right. The experiment shows a noticeable shift, highlighting the critical need to re-zero firearms after suppressor installation before engaging in hunting or tactical scenarios.

Quick Summary

Adding a suppressor to a rifle almost always causes a change in the point of impact, often around two inches up, down, left, or right. This shift is unpredictable, so it is crucial to re-zero your firearm after attaching a suppressor before use.

Frequently Asked Questions

Does adding a suppressor to a rifle always change the point of impact?

Yes, it is very common and almost always observed that there is a change in the point of impact when a suppressor is attached or removed from a rifle. This shift is not always predictable in its direction or magnitude.

How much does a suppressor typically shift a rifle's point of impact?

The point of impact shift caused by a suppressor is not highly predictable, but it's very common to see a movement of about two inches, which can be up, down, left, or right from the original zero.

Can a suppressor improve rifle accuracy?

Yes, it's frequently observed that adding a suppressor to a rifle can actually improve the shooter's group size. This is often attributed to increased barrel harmonics and reduced shooter-induced flinching due to suppressed noise.

What is the most important takeaway when using a suppressor on a rifle?

The key takeaway is that it is critically important to re-zero your rifle after attaching a suppressor. You must confirm your zero before taking the rifle into the field for hunting or any critical application.
