Built around Proof Research's signature \u003cstrong\u003ecarbon fiber-wrapped\u003c\/strong\u003e construction over a \u003cstrong\u003estainless steel\u003c\/strong\u003e core, this barrel drops weight versus an all-steel blank while retaining the rigidity and heat dissipation needed for sustained strings of fire. The \u003cstrong\u003e1:8 PXT\u003c\/strong\u003e rifling twist stabilizes a wide range of bullet weights for both target and duty use, and the barrel is cut on an \u003cstrong\u003eintermediate\u003c\/strong\u003e gas-system length for reliable cycling across AR-15 platforms. It is finished with a \u003cstrong\u003e1\/2x28\u003c\/strong\u003e threaded muzzle for direct installation of standard AR-15 muzzle devices and compensators.\u003c\/span\u003e\u003c\/p\u003e","brand":"Proof Research","offers":[{"title":"Default Title","offer_id":55084447564098,"sku":"198885","price":1140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_dc3e736a-addb-4fbd-9581-7ad69517e87d.png?v=1784769104","url":"https:\/\/centerfiresystems.com\/products\/proof-research-pr15-223-wylde-16-1-8-pxt-carbon-fiber-ar-15-barrel","provider":"Centerfire Systems","version":"1.0","type":"link"}
