Facts about development and production of Bramit sound supressor for Mosin rifle

First efforts to create sound suppressor in USSR were made at the beginning of 1930’s. In 1931 was tested sound suppressor for DP machine-gun. In 1932-1938 were tested suppressors created by Gulevskiy (1932), Schahnovsky (1934), 3 variations created by NIPSVO* (1938), Kondrashov (1938) and Kriger (1938).

All efforts were not successful, and all tested suppressors were heavy, rifles with them show worse grouping, and they did not decrease sound level to necessary. One of the main reason of unsuccessful efforts was use of supersonic ammunition.

In June, 1940 was tested suppressor, created by brothers Mitin. BraMit mean “brothers Mitin” (Братья Митины). It was attached to Mosin barrel same way as bayonet. Lengt was 147 mm, diameter – 32 mm. In December, 1940, after succesful tests Bramit was accepted to service. Serial production was started in the second half of 1941.

Special cartridge was created for a suppressor. Maximal speed of the bullet was 260 meters per second (subsonic speed). In this cartridge was used light bullet. Firing with regular bullets was prohibited. Early cartridges had bullet and bottom of the case painted by green varnish, 1942 cartridges with steel case were all painted with green varnish, later cartridges with steel case were all painted with black varnish, or have a bullet painted in black.

In 1940-1941 cartridges were produced at Ulianovsk ammunition factory #3, later – at factory #543, Kazan

At first one rubber plug was added to 60 cartridges. But first winter showed that because of extremely cold weather plug was ruined after 15-20 shoots. After this was designed winter type of plug, and old type was used for warmer weather. In 1943 2 types of plugs were replaced with one type, that was made from Lend Lease aviation rubber, and can be used in winter or summer.

When there was no special cartridges, it was allowed to use modified regular cartridge with light bullet. Bullet was removed from case, and only 1\3 of powder was left inside the case. Than bullet was installed  at their place. Use of regular bullets can’t injure the shooter, but can destroy rubber plug. Grouping with Bramit suppressor was the same as without it. Maximal distance of use was 300 m . When Bramit was installed, sight settings at the rifle must be changed – 7 for 100m, 8,5 for 150m, 9,5 for 200m, 11 for 250 m, 12 for 300.

Currently there is no published information about early period of Bramit production in 1941. Since 1942 Bramit suppressors were produced at 2 factories – #536 NKV (NKV- Peoples Commissariat of Armament)  in Tula and #621 NKLP (NKLP – Peoples Commissariat of Light Industry) in Kockchetav. Plant #536 was created at the place of evacuated to Mednogorsk plant #314. In February, 1942 factory start production of regular and sniper Mosin rifles. Production of Bramit suppressors was started in May, 1942 and ended at December, 1942. Totally factory #536 produced 58940 Bramit’s.

Another factory that must produced Bramit’s was Podolsk plant #460. But by unclear reasons this factory did not started production of Bramit’s. Later instead of factory #460 in documents is mentioned plant #621 NKLP in Kokchetav. It produced Bramit’s since 1942 to 1 quarter of 1944.
