{"product_id":"ultradyne-athena-linear-comp-1-2x28","title":"Ultradyne USA Athena Linear Compensator 1\/2x28 – AR-15 \u0026 .223\/5.56 Rifles","description":"\u003cp\u003eThe Ultradyne USA Athena Linear Compensator redirects muzzle blast and pressure forward, away from the shooter and nearby personnel. Unlike traditional compensators that vent gases to the sides, this linear comp minimizes lateral concussion, making it ideal for indoor ranges, shooting from covered positions, or any scenario where reducing side blast matters. It still provides recoil reduction through its forward-venting design while keeping your firing line neighbors happier.\u003c\/p\u003e\u003cp\u003eMachined from 416 stainless steel with a durable black nitride finish, the Athena installs on any firearm with 1\/2x28 threads—standard for AR-15 platforms chambered in .223 Remington or 5.56 NATO. Installation is straightforward with a crush washer or shim kit for proper timing. The low-profile design adds minimal length while maintaining a clean sight picture.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Linear Compensator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2x28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 416 Stainless Steel\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, .223 Remington, 5.56 NATO rifles with 1\/2x28 threaded barrels\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ultradyne USA","offers":[{"title":"Default Title","offer_id":47943770964223,"sku":"UD10660","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1291946.jpg?v=1766599759","url":"https:\/\/doublestackstore.com\/products\/ultradyne-athena-linear-comp-1-2x28","provider":"Double Stack Store","version":"1.0","type":"link"}
