The kit uses the classic fixed-stock \u003cstrong\u003eA2-style\u003c\/strong\u003e rifle buffer tube, the longer non-collapsible pattern designed to mount traditional \u003cstrong\u003eA2 buttstocks\u003c\/strong\u003e, and pairs it with a \u003cstrong\u003e.308 carbine buffer\u003c\/strong\u003e and action spring.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe \u003cstrong\u003eA2 buffer tube\u003c\/strong\u003e is dimensionally longer than the modern collapsible Mil-Spec carbine tube and only accepts fixed or A2-pattern buttstocks, making this kit a direct drop-in for \u003cstrong\u003eAR-10\u003c\/strong\u003e builders running a classic fixed rifle stock. The shorter \u003cstrong\u003eCAR-style buffer\u003c\/strong\u003e is tuned for \u003cstrong\u003e.308\u003c\/strong\u003e carriers so the action cycles reliably.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe tube is machined from lightweight \u003cstrong\u003ealuminum\u003c\/strong\u003e to keep overall rifle weight down while providing the strength needed at the receiver extension.
