Originally developed for \u003cstrong\u003eIsraeli counter-terrorism units\u003c\/strong\u003e as a primary combat stock, the GL-Core S CP brings that mission-focused design to the commercial AR platform, integrating an \u003cstrong\u003eadjustable cheek-rest\u003c\/strong\u003e for a consistent, optic-friendly cheek weld during dynamic engagements.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe stock body is molded from \u003cstrong\u003eblack fiberglass-reinforced polymer\u003c\/strong\u003e, giving the GL-Core S CP a lightweight yet rugged build that shrugs off recoil and field abuse. An integrated \u003cstrong\u003eadjustable cheek-rest\u003c\/strong\u003e lets the shooter dial in height for use with red dots, low-power variable optics, or traditional iron sights, while the \u003cstrong\u003eCQB profile\u003c\/strong\u003e keeps the package compact for fast shoulder transitions and a tight cheek weld behind the optic.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eDesigned to mount directly to a standard \u003cstrong\u003eMil-Spec buffer tube\u003c\/strong\u003e (tube not included), the GL-Core S CP bolts up to AR-15 and M4 lower receivers and provides a clean drop-in upgrade. The \u003cstrong\u003eblack\u003c\/strong\u003e finish sits naturally on most rifle builds, delivering an \u003cstrong\u003eIsraeli-spec CQB buttstock\u003c\/strong\u003e to any AR-platform shooter.\u003c\/span\u003e\u003c\/p\u003e","brand":"FAB Defense","offers":[{"title":"Default Title","offer_id":54997304508738,"sku":"122679","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_0f3c956d-8547-404f-b7ce-5785dc2d077b.png?v=1784347259","url":"https:\/\/centerfiresystems.com\/products\/fab-defense-gl-core-s-cp-cqb-ar-15-m4-buttstock-w-adjustable-cheek-rest-black","provider":"Centerfire Systems","version":"1.0","type":"link"}
