The VZ52\/57 is a conversion chambered in 7.52x39mm rather than the defunct 7.62x45mm.<\/p>\n\n\n\n<p>Czechoslovakia adopted VZ52 pattern in 1952 and the nation became a Warsaw pact member in 1955. Some, but not all, VZ52 were subsequently converted to take the standard Russian ammunition. The conversion was achieved in a novel manner: the smaller 7.62&#215;39 chamber was pinned within the larger 7.62&#215;45 chamber, the barrel remained original. I expect that the bolt carrier would have been given weight reduction cuts to increase reliability of cycling, as the 7.62&#215;39 carries \u224820% less energy than the 7.62&#215;45, but the author is yet to confirm this. Production of conversions likely stopped around the time production of 7.62&#215;39 VZ58 began. Some VZ52\/57s were given as aid to Czechoslovakia\u2019s Warsaw Pact allies such as Vietnam and Cuba.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"232\" data-id=\"976\" src=\"http:\/\/armsjournal.net\/wp-content\/uploads\/2023\/02\/1347B2F9-2957-4900-93B5-57F0313A00E1-1024x232.jpeg\" alt=\"\" class=\"wp-image-976\" srcset=\"https:\/\/armsjournal.net\/wp-content\/uploads\/2023\/02\/1347B2F9-2957-4900-93B5-57F0313A00E1-1024x232.jpeg 1024w, https:\/\/armsjournal.net\/wp-content\/uploads\/2023\/02\/1347B2F9-2957-4900-93B5-57F0313A00E1-300x68.jpeg 300w, https:\/\/armsjournal.net\/wp-content\/uploads\/2023\/02\/1347B2F9-2957-4900-93B5-57F0313A00E1-768x174.jpeg 768w, https:\/\/armsjournal.net\/wp-content\/uploads\/2023\/02\/1347B2F9-2957-4900-93B5-57F0313A00E1-1536x348.jpeg 1536w, https:\/\/armsjournal.net\/wp-content\/uploads\/2023\/02\/1347B2F9-2957-4900-93B5-57F0313A00E1-2048x464.jpeg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n\n\n<p>The example of a VZ52\/57 lives in Danmark in the hands of a private sportsman.
