The GP-21 (Russian: Гражданский Противогаз — "Civilian Gas Mask") is manufactured in the Russian Federation by Tambovmash.
Overview[]
The GP-21 is a gas mask kit that is available for purchase in the Russian Federation and in some cases issued to civilians in Russia. It has been available / issued from ~2010 to present day. The Kit is dubbed the GP-21 where as the facepiece is actually named the MP-3. It has a flexible lenses that are bonded to the mask similarly to the MCU-2 series, MSA Millennium, and MSA Advantage gas masks.
The MP-3 has a six-point rubber head harness. All of the straps can be quickly adjusted, in contrast to predecessor masks.
The MP-3 facepiece has two 40mm GOST inlets, with a plug for the one not in use, an orinasal cup, and a voice diaphragm directly in the front. The exhale valve and voice diaphragm is nearly identical to that of the diaphragms on the PMK series of masks.
PMK-5 Nomenclature & Information[]
The PMK-5 was Tambovmash's attempt to win a contract from the Russian military to introduce a new military mask. The project was built on the newly created MP-3 facepiece, however, the project was rejected by the Russian military and the PMK-5 project was abandoned in favor of PMK-4. Today, the MP-3 is still called the PMK-5 from time to time, however, the PMK-5 is no longer in production.
Military Usage[]
While the GP-21 kit and MP-3 facepiece has never been in official use, there has been some cases where the mask is used by some Russian Special Forces groups.
Russian Special Forces groups are permitted to purchase and use their own equipment, that being said, it is believed that some groups / members use the mask in favor of it over the other masks of the PMK series.

Sizes & Sizing Information[]
The MP-3 comes in two different sizes. Size 1 and size 2 which denote medium and large.
Determining size:
The selection of the required size is determined by the sum of the horizontal and vertical circumferences. The horizontal head circumference is determined by measuring the head size in a line running above the eyebrows, 2-3 cm above the edge of the auricle and behind through the most prominent point of the head (look at the picture 1).
The vertical head circumference is determined by measuring the head in a line through the top of the head, cheeks and chin (look at the picture 2).
For heads measuring up to and including 123.5 cm size 1 will work best.
For heads measuring more than 123.5 cm size 2 will work best.
