Polish Military Surplus MP4 Bulldog Protective Gas Mask Kit M4607 91650096 UPC 871373624755
Product Description
The Polish Military Surplus MP-4 "Bulldog" Gas Mask Kit (SKU: M4607 / UPC: 871373624755) represents an iconic Cold War individual protective respirator issued throughout the Polish Armed Forces (Wojsko Polskie). Developed by PSO Maskpol as an authorized Warsaw Pact adaptation of the proven United States military M17 cheek-filter platform, the MP-4 replaces cumbersome external canisters with internal, conformal cheek-mounted filter elements. This flush-fit architecture eliminates outboard snag hazards and allows riflemen to achieve an unobstructed, natural cheek weld against the comb of standard service rifles, making it a prized acquisition for military surplus collectors, living historians, and tactical reenactors.
Molded from heavy-gauge vulcanized elastomer, the MP-4 facepiece delivers substantial chemical resilience and a dependable peripheral facial seal across varied environmental conditions. The optical suite features dual oversized triangular eyepieces manufactured from impact-resistant optical glass, swaged tightly into corrosion-resistant metal bezels to maintain structural rigidity under stress. Inhalation airflow draws through the lateral cheek chambers and routes past the interior optical lenses before entering the oral-nasal mask, providing passive defogging and thermal equilibrium during intense respiration, while a robust forward-facing exhalation valve exhausts moisture and spent air rapidly.
Retention is anchored by a heavy-duty 6-point elasticized webbing harness integrated into a contoured rubber occipital head cradle, distributing clamping pressure symmetrically across the crown to mitigate hot spots during prolonged wear. The central chin assembly features an acoustic voicemitter membrane designed to preserve vocal clarity for command transmission and team communications without breaking the mask seal. Supplied as a comprehensive surplus bundle complete with spare internal cheek filter elements, this MP-4 "Bulldog" assembly is an authentic, rugged addition to any vintage military gear collection or tactical gear staging display.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Standard adult head profiles (accommodates adult medium to large facial dimensions). CRITICAL: This mask does NOT utilize a 40mm NATO (STANAG 4155 / Rd 40x1/7") threaded port and CANNOT accept standard 40mm canister filters. The included W-P4 cheek filters represent surplus military elements; due to expired military shelf life, this respirator assembly is sold strictly for novelty, historical collecting, costume, and training display purposes, and is NOT rated for active CBRN environments, toxic industrial chemicals, or smoke-filled atmospheres.
- Ensure the host workspace is sanitized and confirm the surplus mask is unboxed on a clean bench surface free of debris and solvent contamination.
- Invert the rubber cheek flaps from the inside of the mask outward to access the internal filter cavity chambers flanking the nose cup.
- Seat the left and right curved cheek filter elements into the cavities, aligning the perimeter seals and intake ports with the external facepiece retaining rings.
- Smooth the internal cheek linings back to their operational contour, inspect the central voicemitter and exhalation valve for free movement, and verify the oral-nasal cup fitment.
- Don the mask chin-first, draw the 6-point elastic suspension harness over the crown, adjust strap tension symmetrically from bottom to top, and verify negative seal integrity by covering the external cheek intake ports and gently inhaling.
