This video demonstrates testing a CMMG Zeroed 9mm suppressor on an AR-15 platform, initially shown on a G-Force Arms Jaba. The experiment reveals that while the suppressor is designed for 9mm, it can be used on a .223 AR-15, though it gets very hot. The reviewer notes significant sound reduction, effective recoil mitigation, and reduced gas blowback to the face, comparing the sound to unsuppressed .22LR.

Quick Summary

A 9mm suppressor, like the CMMG Zeroed can, can be attached to an AR-15 chambered in .223 Remington. While it offers benefits like recoil mitigation and reduced gas blowback, it's crucial to note that the suppressor can overheat rapidly due to the higher pressure of the .223 cartridge.

Frequently Asked Questions

Can a 9mm suppressor be used on an AR-15 chambered in .223 Remington?

Yes, a 9mm suppressor can physically be attached to an AR-15 chambered in .223 Remington. However, the suppressor's diameter is larger than typically needed for .223, and it can get very hot with rapid firing due to the increased pressure and heat of the .223 cartridge.

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

When using a 9mm suppressor on an AR-15, users can experience significant recoil mitigation and a noticeable reduction in gas blowback to the face. The sound reduction is also a primary benefit, though the perceived sound level can vary.

How does a 9mm suppressor perform on a .223 AR-15 in terms of sound?

The sound reduction achieved by using a 9mm suppressor on a .223 AR-15 is described as making the firearm sound similar to shooting an unsuppressed .22LR. While suppressed, it's not completely silent, but the report is significantly diminished.

What are the potential drawbacks of using a 9mm suppressor on a .223 AR-15?

A primary drawback is the suppressor's tendency to overheat quickly, especially when firing multiple rounds or in bursts. The larger diameter of a 9mm suppressor is also a consideration compared to suppressors specifically designed for .223 caliber firearms.
