The extended length reduces felt recoil and provides a more stable shooting platform for precision rifle setups while maintaining the adjustability of a collapsible design.\u003c\/p\u003e\u003cp\u003eConstructed from reinforced polymer with an anti-slip rubber buttpad, this stock installs on any mil-spec carbine buffer tube. The longer length adds approximately 0.8 inches compared to standard collapsible stocks, making it ideal for larger-frame shooters or those running optics that require proper eye relief. Six-position adjustment allows fine-tuning for different shooting positions and clothing layers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Collapsible Precision Stock (Long)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16, M4 (mil-spec buffer tube)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Reinforced polymer with rubber buttpad\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Coyote Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable:\u003c\/strong\u003e Yes (6 positions)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Direct attachment to mil-spec carbine buffer tube\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B5 Systems","offers":[{"title":"Default Title","offer_id":47935216582911,"sku":"B5CPS-1414","price":218.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2855524.jpg?v=1766481489","url":"https:\/\/doublestackstore.com\/products\/b5-collapsible-prec-stk-lng-cb","provider":"Double Stack Store","version":"1.0","type":"link"}
