MIRA Safety CM-7M military gas mask provides the ultimate defense against chemical, biological, radiological, and nuclear (CBRN) agents when used with filters or a breathing apparatus. This full-face respirator is designed with military-grade technology for comprehensive protection against hazardous gases, vapours, and aerosols. It was developed in cooperation with Czech Army specialists for advanced tactical capability with a wide array of optics.
This NATO gas mask is made with bromobutyl rubber for extraordinary protection against all known chemical warfare agents, along with biological, nuclear, radiological, and industrial chemical agents. The tactical gas mask is designed to withstand long-term use in any weather condition and features a comfortable hypoallergenic construction to reduce carbon dioxide content and prevent fogging.
The CM-7M is manufactured under the supervision of the Czech Ministry of Defense and meets EN 136 (Class III) and EN 148-1 standards. Its dual lens configuration provides superior depth perception for rifle iron sights or in combat and a NATO-standard filter canister (NOT included, can be bought separately see MIRA Safety CBRN Gas Mask Filter) can be mounted on either (or both) side of the military mask to make it easier to aim a gun whether right- or left-handed.
The CM-7M hazmat mask is equipped with a drinking system and is compatible with CamelBak hydration systems. The inner mask features comfortable hypoallergenic construction that reduces the content of carbon dioxide in the mask and regulates the flow of inhaled air to prevent fogging for more comfortable all-day use. The inhalation chambers on this army gas mask are fitted with the Rd 40 x 1/7” thread in accordance with the EN 148-1 (NATO) standard. This ensures compatibility with the widest range of filters readily available on the market today.
- Tapered design to allow for cheek weld on rifles and other long guns
- Recessed binocular visor for aiming with night vision optics and red dot sighting systems
- Low profile cut allows for integration with modern ballistic helmets and ear protection
CM-6M Vs CM-7M
The CM-7M is specially designed for use with optics and operating a rifle. Features include a dual recessed visor system for eye relief, along with a contour above the inhalation valve for a closer cheek weld. These features come at the expense of a wide field of view, and this is where the CM-6M shines. Think of the CM-7M and CM-6M as different tools for different jobs.
Please Note: Filters are NOT included. For Compatible Gas Filter Canisters please see CBRN NBC-77 SOF 40mm Gas Mask Filter.

How to Store your Gas Mask
The CM-7M tactical gas mask must be stored in a dark, cool and dust-free place free from sudden temperature changes. The storage room should be ventilated regularly.

Fuels, solvents, lubricants and other inflammable substances, including chemicals, must not be stored with masks. Moreover, there must not be any electrical machines or appliances that produce sparks or discharges during operation (ozone creation). Avoid deformation of the rubber parts of the face-piece and internal CBRN gas mask during storage.

How to Choose the Right Size:
To size yourself, it would require a device called a faciometer which is not very common.
Size 2 (medium) fits 95% of the population, so if you're an average size person, we would suggest size 2. For smaller than average people who weigh 58kg (130lb) or less, with thin faces, we would suggest size 1 (small). For users over 113kg (250 lbs) and wide faces, go with large.
You will know the size is right if you do a negative pressure test (blocking the inhalation valve and taking a deep breath), and the mask seals tightly to your face.
