Gas Masks at Keep Shooting
Keep Shooting carries one of the deepest selections of authentic military surplus gas masks in the United States — Cold War-era NBC respirators from the Soviet Union, Czechoslovakia, Poland, Hungary, Yugoslavia, France, and the Netherlands, plus modern commercial CBRN respirators from Mestel Safety, 40mm NATO replacement filters, and full chemical protective suits. Every military gas mask in our catalog is a genuine government-issue piece released from national NBC (Nuclear, Biological, Chemical) stockpiles after the end of the Cold War, and every product is sold with full disclosure of its intended use — collecting, costume and theatrical use, historical reference, and general emergency preparedness.
The single most recognizable Cold War gas mask in the world is the Soviet GP-5 — and we carry it both as a bare mask and as the complete GP-5 Gas Mask Kit with original GOST-pattern filter, carry bag, and accessories. The GP-5 was the standard civil defense respirator of the Soviet Union from 1970 onward, manufactured in the tens of millions and issued to schools, factories, government buildings, and military reserve units across the entire USSR and Warsaw Pact. Its distinctive round-eyepiece, full-face design with the integrated filter on the front has appeared in countless Cold War films, music videos, and post-apocalyptic media — it is the gas mask in popular imagination. The GP-5 accepts the original GOST 40mm thread filter that ships with the kit, but it is important to know that the GOST thread is not the same as the NATO 40mm thread: a GOST filter will thread onto a NATO mask, but a NATO STANAG 4155 filter will not thread onto a GOST mask. The Russian GP-5 we sell is the same Russian-built design as the Soviet original.
Beyond the GP-5, our European NBC mask collection covers the major Warsaw Pact and NATO designs of the Cold War. The Czech M10 Gas Mask — full name M10M — is one of the more advanced Eastern Bloc respirators of the late Cold War, with a wide field of view, a drinking tube, and a 40mm filter port. We carry both the mask itself and replacement M10 Gas Mask Filters. The Polish MP4 and Polish MC-1 (Polish Army NBC) gas masks were standard issue to the Polish People's Army and the modern Polish Armed Forces; they share the wide-vision full-face design that Eastern European designers favored and accept any 40mm filter. The Hungarian M74 Gas Mask is a Warsaw Pact-era full-face respirator from the Hungarian People's Army. The Yugoslavian M1 Gas Mask comes from the JNA NBC stockpile and is a distinctive design with separate filter canister and hose. The French Army Surplus Gas Mask Filter is the standard French Armée de Terre 40mm replacement filter from the French CBRN program.
For modern commercial protection, we also carry the Mestel Safety SGE 400/3 Gas Mask — an Italian-made full-face respirator with a panoramic visor, three 40mm filter ports (left, right, and front, configurable for left- or right-handed users), and a built-in drinking port. The SGE 400/3 is one of the most respected commercial CBRN masks on the market and is widely used by law enforcement, EMS, search-and-rescue teams, and serious preparedness buyers who want a brand-new, in-warranty mask rather than a Cold War surplus piece. For full-body protection, our Bio-Chemical Protective Suit ships as a complete set with hood and over-boots for use alongside any 40mm respirator, and the Dutch M82 NBC Parka is an authentic Royal Netherlands Army cold-weather chemical protective parka from the Cold War-era Dutch CBRN program.
Filters are the heart of any gas mask system, and we stock replacement filters for the major thread standards. The 40mm NATO filter is the dominant world standard, codified in NATO STANAG 4155 and EN 148-1 (Rd 40×1/7"), and any mask built to this standard accepts any 40mm NATO filter from any manufacturer. Our ADG 40mm NIOSH Gas Mask Filter is a US-made NIOSH-approved commercial filter that fits any STANAG 4155 mask, and our generic Gas Mask Filter listing covers standard 40mm NATO replacements. A critical note on filters: every NBC filter has a finite shelf life (typically 5 to 25 years depending on the manufacturer and storage conditions), the expiration date is printed on the filter label, and once the seal is broken the protective service life drops to roughly 8–24 hours of use. Always check the date stamp before relying on any filter, store sealed filters in a cool dry environment away from direct sunlight, and replace any filter that is past its printed expiration.
Important disclosure: Keep Shooting sells these gas masks as collectible military surplus and general-purpose respiratory equipment. Most of our surplus masks are decades old, the original-issue filters that ship with them are typically beyond their original certified service life, and none of these surplus respirators are currently NIOSH-certified or warrantied for industrial respiratory protection. They are sold for collecting, film and theatrical costume use, historical study, reenactment, museum display, and general preparedness — not for use in known chemical or biological environments where life depends on the equipment. Buyers who require certified CBRN protection for occupational or active emergency use should select the Mestel SGE 400/3 with current-production filters, or consult a professional respiratory protection supplier.
