This Supressor Is Meant For 9mm!

Duration: 1:32

This video demonstrates the compatibility and performance of a 9mm suppressor on an AR-15 platform. The test involves attaching a CMMG Zeroed Suppressor to an AR-15 (specifically a Davidson Defense A2 clone) after initially showing it on a G-Force Arms Jaba. Key observations include the suppressor's effectiveness in sound reduction and recoil mitigation, but also significant heat buildup and gas blowback when used on a rifle caliber. The speaker notes that while it functions, it's designed for 9mm pistol cartridges.

Quick Summary

A 9mm suppressor, such as the CMMG Zeroed, can be attached to an AR-15, but it's not ideal. While it offers some recoil mitigation and sound reduction comparable to unsuppressed .22LR, it rapidly overheats and produces significant gas blowback on rifle calibers like .223/5.56.

Frequently Asked Questions

Can a 9mm suppressor be used on an AR-15?

Yes, a 9mm suppressor like the CMMG Zeroed can be physically attached to an AR-15. However, testing shows it leads to rapid heat buildup and significant gas blowback, indicating it's not ideal for rifle calibers like .223/5.56 compared to suppressors designed for those cartridges.

What are the risks of using a 9mm suppressor on an AR-15?

The primary risks include excessive heat buildup on the suppressor after minimal firing, potentially leading to damage or discomfort. Significant gas blowback to the shooter's face is also common, reducing the shooting experience and potentially impacting reliability.

How does a 9mm suppressor perform on an AR-15 in terms of sound?

When a 9mm suppressor is used on an AR-15 chambered in .223/5.56, the sound suppression is noted to be comparable to shooting an unsuppressed .22LR firearm. This suggests it offers some sound reduction but is not as effective as a dedicated rifle suppressor.

Does a 9mm suppressor help with recoil on an AR-15?

Yes, the video indicates that the 9mm suppressor does provide some recoil mitigation when attached to an AR-15. While not its primary design purpose for this platform, users may experience a slightly softer shooting impulse.
