This extended-length buffer tube provides additional positions for length of pull adjustment and allows shooters to run the proven A5 recoil system on their .308 AR rifles, improving recoil impulse management and carrier timing compared to standard carbine extensions.\u003c\/p\u003e\u003cp\u003eMachined from 7075-T6 aluminum with a Type III hard-coat anodized finish, this receiver extension features a 6-position design with integrated QD sling swivel mounting points at the rear. The A5-length design creates additional buffer travel space, which can reduce felt recoil and bolt carrier group bounce, particularly beneficial for tuning large-frame ARs with adjustable gas blocks or suppressed configurations. Compatible with standard AR-10\/SR-25 pattern lower receivers. Requires A5 buffer and rifle-length action spring (not included).\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Receiver Extension \/ Buffer Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-10, SR-25, .308 AR pattern rifles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Type III Hard-Coat Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositions:\u003c\/strong\u003e 6-Position Adjustment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e QD sling swivel mounting, A5 buffer system compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires castle nut and end plate (may not be included), A5 buffer and rifle spring required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLTOR Weapon Systems","offers":[{"title":"Default Title","offer_id":47939096477951,"sku":"VLTRE-10-A5SR","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2885906.jpg?v=1766539337","url":"https:\/\/doublestackstore.com\/products\/vltor-rcvr-ext-ar-10-a5-s-rail-6-pos","provider":"Double Stack Store","version":"1.0","type":"link"}
