It is a direct replacement for a Mil-Spec pistol buffer tube, dropping into any standard AR-15 lower that accepts a pistol-length extension.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe PS-BTP4 is milled from \u003cstrong\u003e6061-T6 aluminum\u003c\/strong\u003e and finished in a durable \u003cstrong\u003eType II anodized black\u003c\/strong\u003e coating for corrosion resistance and a low-glare surface. The extension is built to \u003cstrong\u003eMil-Spec\u003c\/strong\u003e dimensions, ensuring proper fit with standard castle nuts, end plates, and pistol buffer\/spring assemblies.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eWhat sets this buffer tube apart from a standard solid extension is the \u003cstrong\u003e14 pass-through skeleton cuts\u003c\/strong\u003e machined along its length. The openings remove excess material to drop weight and give the tube a distinctive skeletonized look that matches well with other lightweight AR-15 pistol components. The PS-BTP4 is sold as the buffer tube only; spring, buffer, castle nut, and pistol brace are sold separately.\u003c\/span\u003e\u003c\/p\u003e","brand":"JE Machine Tech","offers":[{"title":"Default Title","offer_id":55480491344194,"sku":"201047","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_2a8788fe-4f2e-4d10-95cc-9df69c0cfbcc.png?v=1785584340","url":"https:\/\/centerfiresystems.com\/products\/je-machine-tech-ps-btp4-ar-15-pistol-buffer-tube-skeletonized-black","provider":"Centerfire Systems","version":"1.0","type":"link"}
