The pingless design features tines tuned to dampen resonance, reducing audible signature when shooting unsuppressed. This version is sized specifically for pin-and-weld installation on 13.7\" barrels to meet the 16\" legal minimum without requiring an NFA tax stamp for short-barreled rifles.\u003c\/p\u003e\u003cp\u003eMachined from heat-treated steel with a durable black oxide finish, this flash hider features 5\/8x24 threading common to .308\/7.62 caliber rifles. Installation requires permanent pin-and-weld by a qualified gunsmith to achieve legal overall length. Once installed, the 51T mount allows rapid attachment and detachment of compatible AAC suppressors. Use of AAC suppressors requires appropriate NFA paperwork and tax stamp.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Flash Hider \/ Suppressor Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 5\/8x24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e 51T Quick-Detach (Pingless)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Pin \u0026amp; Weld (Permanent)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e 13.7\" .308\/7.62 rifles with 5\/8x24 threads\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Advanced Armament Corp","offers":[{"title":"Default Title","offer_id":47943428964607,"sku":"AACO65034","price":105.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5505794.jpg?v=1766573480","url":"https:\/\/doublestackstore.com\/products\/aac-51t-pingless-fh-5-8x24-13-7-pwb","provider":"Double Stack Store","version":"1.0","type":"link"}
