{"product_id":"pws-1-2x28-piston-blk","title":"Pws 1\/2x28 Piston Blk","description":"Primary Weapons Systems was formed by firearm enthusiasts in 2008. Starting out by producing muzzle devices, they tested their compensators on all different types of rifles - from M4s to AK-47s. After using both styles of rifles in testing with high round counts, the difference in maintenance needed was both astounding. From that basic realization, the PWS long-stroke piston system was born; keeping the core values of the AR-15 design, while also lessening the need for maintenance in high-volume fire situations and adverse conditions. The 1\/2x28 piston allows the use of PWS suppressors on 1\/2x28 threads.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures\u003c\/b\u003e :\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e1\/2x28\u003c\/li\u003e\n\u003cli\u003eAnodized Finish\u003c\/li\u003e\n\u003cli\u003eBlack\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Primary Weapons Systems","offers":[{"title":"Default Title","offer_id":47223152214234,"sku":"RPLPWSPISTON-1-2X28","price":79.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/3886\/3834\/files\/RPLPWSPISTON-1-2X28.jpg?v=1766011949","url":"https:\/\/fargostrategicmachining.com\/products\/pws-1-2x28-piston-blk","provider":"Fargo Strategic Machining","version":"1.0","type":"link"}
