This buffer tube replaces standard mil-spec tubes and features WMD's proprietary NIB-X nickel boron coating, which offers exceptional hardness, corrosion resistance, and self-lubricating properties. Shooters who run their rifles in harsh environments or who want reduced friction during stock adjustment will appreciate the NIB-X finish over standard phosphate or anodized tubes.\u003c\/p\u003e\u003cp\u003eManufactured from 7075-T6 aluminum with a durable NIB-X silver finish applied to all surfaces including the threads. Installation is straightforward for anyone familiar with AR-15 lower assembly—requires a castle nut wrench and staking tool for proper installation. The mil-spec diameter ensures compatibility with standard carbine stocks from all manufacturers. Threading is precise and the finish is uniform, allowing smooth stock movement without binding.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Carbine Buffer Tube (Receiver Extension)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, mil-spec carbine stocks\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 NIB-X Nickel Boron (Silver)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (requires castle nut wrench and staking tool)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Buffer tube only (castle nut and end plate not included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WMD Guns","offers":[{"title":"Default Title","offer_id":47939838607615,"sku":"WMDNIBXBT","price":36.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5584901.jpg?v=1766548304","url":"https:\/\/doublestackstore.com\/products\/wmd-buffer-tube-carbine-nib-x-silver","provider":"Double Stack Store","version":"1.0","type":"link"}
