{"product_id":"angstadt-9-40-45acp-10oz-buffer-kit","title":"Angstadt Arms 9\/40\/45 ACP 10oz Buffer Kit – PCC AR-Platform","description":"\u003cp\u003eThe Angstadt Arms 10oz Buffer Kit is engineered specifically for pistol-caliber carbines chambered in 9mm, .40 S\u0026amp;W, and .45 ACP built on AR-platform lowers. This heavier buffer weight helps regulate bolt carrier velocity in blowback-operated PCCs, reducing felt recoil and improving cycling reliability with a wider range of ammunition loads. Proper buffer weight is critical in direct blowback systems where there's no gas system to moderate timing.\u003c\/p\u003e\u003cp\u003eThe kit includes a machined steel buffer housing with tungsten weights totaling 10 ounces, plus a heavy-duty buffer spring designed to work in concert with the increased mass. Installation is straightforward—simply remove your existing buffer and spring from the receiver extension, then install this kit. Compatible with standard carbine receiver extensions on AR-pattern pistol-caliber builds. Not for use in rifle-caliber gas-operated systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pistol Caliber Carbine Buffer Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-pattern PCCs in 9mm, .40 S\u0026amp;W, .45 ACP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuffer Weight:\u003c\/strong\u003e 10 ounces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel housing with tungsten weights\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Buffer assembly and heavy-duty spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in replacement for standard carbine buffer systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Angstadt Arms","offers":[{"title":"Default Title","offer_id":47944016396543,"sku":"ANGAA40BUFKIT","price":90.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5565549.jpg?v=1766612227","url":"https:\/\/doublestackstore.com\/products\/angstadt-9-40-45acp-10oz-buffer-kit","provider":"Double Stack Store","version":"1.0","type":"link"}
