Product DescriptionThe Grey Ghost Precision (GGP) AR-10 M-LOK handguard brings the proven MKII rifle handguard design to your AR-10 build. Built from a 6061-T6 aircraft-grade aluminum extrusion, this free-float style handguard features a full-length Picatinny top rail with engraved numerical T-markings for repeatable accessory placement. Installation is straightforward thanks to a non-proprietary barrel nut that does not require timing-tighten the barrel nut to the specified torque, slide the handguard flush to the upper receiver, and secure it with the included fastening screws. Left and right index tabs help prevent rotation under hard use, and M-LOK slot placement provides flexible mounting options for lights, grips, and other accessories.Product Highlights 6061-T6 aircraft-grade aluminum handguard extrusion for a strong, lightweight AR-10 build Full-length Picatinny top rail with engraved T-markings for consistent optic/accessory positioning Non-proprietary barrel nut design (no timing required) for easier installation and alignment M-LOK slots at 3, 6, and 9 o&&';;clock plus forward slots at 1 and 11 o&&';;clock for versatile accessory mounting Anti-rotation index tabs and two fastening screws help keep the handguard secure during use Specs Brand: Grey Ghost Precision Manufacturer Part Number: GGP30815HGOD UPC: 860006002060 Platform/Fit: AR-10 Length: 15 in Attachment System: M-LOK Material: 6061-T6 aircraft-grade aluminum extrusion Top Rail: Full-length Picatinny with engraved numerical T-markings Inside Diameter: 1.380 in Barrel Nut: Non-proprietary; does not require timing Installation Torque (Barrel Nut): 65 ft-lbs Installation Torque (Fastening Screws): Approx. 35 in-lbs Compatibility Notes: Compatible with all forged upper receivers and most billet upper receivers What&&';;s Included: Barrel nut and two fastening screws Wrench Included: No (barrel nut compatible with a standard armorer&&';;s wrench) Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
