Correctly weighted and sized buffers are essential in a straight-blowback 9mm AR upper, and this unit is engineered to the right mass and length for reliable cycling with the bolt carrier and spring combinations common to the 9mm AR platform.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe body is machined from \u003cstrong\u003estainless steel\u003c\/strong\u003e for corrosion resistance and long service life, paired with a \u003cstrong\u003eclear polyurethane\u003c\/strong\u003e rear bumper that cushions the buffer against the back of the buffer tube on each cycle. At \u003cstrong\u003e8.2 ounces\u003c\/strong\u003e and \u003cstrong\u003e4 inches long\u003c\/strong\u003e, the buffer drops into any standard MilSpec receiver extension or pistol buffer tube. Its geometry (approximately 1.05 in high by 2.25 in wide) matches conventional AR buffer dimensions, making it a direct drop-in replacement for the factory unit in a dedicated 9mm build.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003e\u003cstrong\u003eGuntec USA\u003c\/strong\u003e designs and finishes this buffer in the United States to give dedicated 9mm AR owners a long-wearing, properly weighted component. Whether you are assembling a new pistol caliber carbine from scratch or replacing a worn or under-weighted buffer in an existing build, the \u003cstrong\u003eBUF-9\u003c\/strong\u003e provides the materials, weight, and length a 9mm blowback system needs.\u003c\/span\u003e\u003c\/p\u003e","brand":"Guntec USA","offers":[{"title":"Default Title","offer_id":55342290338114,"sku":"ZBUF9","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/alt_846629e1-55dd-4b63-aa4f-5a61db24e61e.jpg?v=1785179637","url":"https:\/\/centerfiresystems.com\/products\/guntec-usa-ar-15-9mm-luger-buffer-4-stainless-steel","provider":"Centerfire Systems","version":"1.0","type":"link"}
