At the very beginning of their use, they were fiber bumpers, and when the fiber of the required thickness could not be obtained, in factories they tried to use rubber, felt or pressed leather for the production of buffers. Such PPSh dampers, as a rule, did not serve for long and the soldiers had to make replacements for them from improvised means. For example, cut from an old boot sole or cast from &#8220;raw rubber&#8221;.<\/p>\n\n\n\n<p>Due to the short service life of the PPSh fiber shutter buffers, textolite ones came later to replace them. They differed not only in the material of manufacture, but also in shape and size. Now, in the 21st century, with the development of technology, the choice of materials has become much wider and we offer our own version of polyurethane bumpers. <\/p>\n\n\n\n<p>In our store, there are two standard sizes of shutter buffers for PPSh \u2014 analogs of the original made of fiber and textolite.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to choose a recoil buffer for PPSh-41?<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blog.polyurethan.ru\/wp-content\/uploads\/2020\/10\/20201022_135929-scaled-e1603355709134-1024x768.jpg\" alt=\"\" class=\"wp-image-13679\" width=\"256\" height=\"192\" srcset=\"https:\/\/blog.polyurethan.ru\/wp-content\/uploads\/2020\/10\/20201022_135929-scaled-e1603355709134-1024x768.jpg?v=1617729352 1024w, https:\/\/blog.polyurethan.ru\/wp-content\/uploads\/2020\/10\/20201022_135929-scaled-e1603355709134-300x225.jpg?v=1617729352 300w, https:\/\/blog.polyurethan.ru\/wp-content\/uploads\/2020\/10\/20201022_135929-scaled-e1603355709134-768x576.jpg?v=1617729352 768w, https:\/\/blog.polyurethan.ru\/wp-content\/uploads\/2020\/10\/20201022_135929-scaled-e1603355709134-1536x1152.jpg?v=1617729352 1536w, https:\/\/blog.polyurethan.ru\/wp-content\/uploads\/2020\/10\/20201022_135929-scaled-e1603355709134-2048x1536.jpg?v=1617729352 2048w\" sizes=\"auto, (max-width: 256px) 100vw, 256px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:55%\">\n<h3 class=\"wp-block-heading\"><strong>Shape and<\/strong> <strong>size<\/strong><\/h3>\n\n\n\n<p>In our online store you will find 2 variants in shape and thickness.
