Featuring a distinctive flag design, this protector ensures your 1\/2x28 threads remain clean and undamaged during transport, storage, or cleaning sessions. Thread protectors prevent cross-threading and make future muzzle device installation smoother by preserving thread integrity.\u003c\/p\u003e\u003cp\u003eMachined to fit standard 1\/2x28 threads found on most AR-15 barrels and .223\/5.56 rifles. The flag relief cuts provide wrench flats for easy hand-tightening and removal without marring. Constructed from durable steel with a protective finish. Hand-tighten only—do not use thread locker or apply excessive torque, as thread protectors are meant to be temporary covers, not permanent installations.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Thread Protector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2x28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Flag relief pattern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, .223\/5.56 rifles with 1\/2x28 threads\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Backup Tactical","offers":[{"title":"Default Title","offer_id":47942175981823,"sku":"BACKFLAG","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1242442.jpg?v=1766570098","url":"https:\/\/doublestackstore.com\/products\/backup-thrd-prtctr-1-2x28-flag","provider":"Double Stack Store","version":"1.0","type":"link"}
