With this kit, you will compress the main spring by pulling back the bolt, like most of the spring powered airsoft bolt action rifle. The volume of air is increasing from 28 cc to 41 cc (+46%), and this huge volume of air will allow you to reach high power with easier priming of the gun. \u003cb\u003e\u003cbr\u003e\u003cbr\u003eSilverback SRS Pull Bolt Conversion Kit\u003c\/b\u003e \u003cbr\u003eFull Metal Construction \u003cbr\u003eMake your SRS Sniper form push cocking system covert to pull-back cocking system\u003cbr\u003e The Spring Provided with this kit develops a muzzle energy of 1.8 joules \u003cbr\u003eSuitable For Silverback SRS Covert Bullpup Sniper \u003cbr\u003e\u003cbr\u003ePackage Include: \u003cbr\u003eModified fibred nylon buttplate spacer \u003cbr\u003eSteel bolt head (welded) and steel cylinder Steel spring guide \u003cbr\u003eAluminium piston with synthetic rubber damper and steel piston end \u003cbr\u003eSynthetic rubber dust cover filled with foam (dust protection and noise reduction) \u003cbr\u003eAPS M140 spring (13 mm outer diameter)\u003c\/p\u003e","brand":"Silverback","offers":[{"title":"Default Title","offer_id":42256683040996,"sku":"SBA-BBA-05","price":69.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/1325\/2580\/products\/sba-bba-05_2_mark_18bd23f6-39b8-4d91-b078-584b0e71e5dc.jpg?v=1640510343","url":"https:\/\/www.ehobbyasia.com\/ko\/products\/silverback-srs-pull-bolt-conversion-kit","provider":"eHobbyAsia","version":"1.0","type":"link"}
