Hot Suppressor! How Hot do they Get?

Published on October 12, 2019
Duration: 8:57

This video demonstrates how quickly a firearm suppressor heats up during rapid firing, specifically with .22, 9mm, and 300 Blackout cartridges. It highlights temperature readings after mag dumps and discusses practical methods for safely storing a hot suppressor, such as using an oven mitt to prevent damage to range bags.

Quick Summary

Firearm suppressors heat up rapidly during rapid fire. After a 33-round mag dump of 300 Blackout, temperatures can reach around 190-193°F. Never store a hot suppressor in nylon gear; use a heat-resistant oven mitt to safely handle and transport it, protecting both the suppressor and your range bag.

Frequently Asked Questions

How hot can a firearm suppressor get after a mag dump?

Firearm suppressors can get extremely hot very quickly. After a 33-round magazine dump with 300 Blackout, temperatures can reach around 190-193 degrees Fahrenheit. Even after just 20 rounds of .22LR, a suppressor can reach approximately 125 degrees Fahrenheit.

What is the best way to store a hot suppressor?

A hot suppressor should never be placed in a nylon pouch or standard range bag as the heat will melt them. A safe method is to use a heat-resistant barbecue oven mitt, peeling it down over the suppressor to protect it and your gear.

How long does it take for a suppressor to cool down?

Suppressors take a significant amount of time to cool down. After firing, the heat soak continues to transfer through the baffles and tube. The video shows a suppressor cooling from over 190°F to 85°F after about an hour and a half in the shade.

Which SilencerCo suppressor is recommended for 300 Blackout?

The presenter recommends the SilencerCo Octane 9 suppressor as being better suited for the 300 Blackout cartridge. While the Octane 45 is more versatile for pistol calibers, the Octane 9 offers superior performance for this specific rifle cartridge.
