{"product_id":"ballistic-bbl-6mm-arc-20-dmr","title":"Ballistic Advantage 6mm ARC 20\" DMR Barrel – AR-15 Platform","description":"\u003cp\u003eThis 20-inch DMR-profile barrel is purpose-built for the 6mm ARC cartridge, delivering the extended sight radius and velocity needed to exploit the round's long-range ballistic efficiency. The 6mm ARC offers superior ballistic coefficients and retained energy compared to traditional .223\/5.56 loads, and this barrel length maximizes those advantages for precision shooting at distance. Ideal for designated marksman setups, long-range target work, or hunters who need flat trajectories past 500 yards.\u003c\/p\u003e\u003cp\u003eManufactured from 4150 Chrome Moly Vanadium steel with a mid-length gas system for reliable cycling and reduced recoil impulse. The barrel features a black nitride finish for corrosion resistance and extended barrel life. Fits standard AR-15 upper receivers with a barrel extension and M4 feed ramps. Requires 6mm ARC bolt and compatible magazines; this is not a drop-in replacement for .223\/5.56 uppers without those changes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e DMR Profile Barrel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 6mm ARC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas System:\u003c\/strong\u003e Mid-Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4150 Chrome Moly Vanadium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 Platform (requires 6mm ARC bolt)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ballistic Advantage","offers":[{"title":"Default Title","offer_id":47941991039231,"sku":"BABL6MM003P","price":261.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2855754.jpg?v=1766569932","url":"https:\/\/doublestackstore.com\/products\/ballistic-bbl-6mm-arc-20-dmr","provider":"Double Stack Store","version":"1.0","type":"link"}
