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 13.5x1 LH piston allows the use of PWS suppressors on 13.5x1 LH threads.\u003c\/p\u003e","brand":"Primary Weapons Systems","offers":[{"title":"Default Title","offer_id":52783270101274,"sku":"PWSPISTON-135X1LH","price":76.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1005\/3179\/8298\/files\/6005515.jpg?v=1788377231","url":"https:\/\/neshaminyoutfitters.com\/products\/pws-13-5x1lh-piston-blk","provider":"Neshaminy Outfitters","version":"1.0","type":"link"}
