While the polymer Bolt B is 13g lighter than the orginial part, this polymer Bolt B has good strength with higher elasticity than the original part.  Therefore, this polymer Bolt B has only 55% weight of the original part, and it assists the bolt to increase the recoil speed and minimize friction around the buffer tube.\u003c\/p\u003e","brand":"Wii Tech","offers":[{"title":"M4 (T.Marui) CNC Polymer Bolt B","offer_id":55513958973764,"sku":"L-WT-53","price":12.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/3613\/2164\/files\/2194-1-850x715.jpg?v=1755860243","url":"https:\/\/www.skirmshop.nl\/en-nl\/products\/m4-tmarui-cnc-polymer-bolt-b","provider":"Skirmshop","version":"1.0","type":"link"}
