The Grey Ghost Precision AR-15 15-inch M-LOK Handguard in Olive Drab (Grey Ghost Precision part no. GGP55615HGOD) is the same free-float handguard design that comes standard on GGP’s own MKII rifles, now available separately for builders. Grey Ghost Precision extrudes the handguard from 6061-T6 aircraft-grade aluminum and finishes it in a Type III Class 2 hard-coat anodized Olive Drab, then machines it to a 1.310-inch inside diameter over a non-proprietary barrel nut that needs no timing. Left and right index tabs keep the handguard from twisting under use, and two fastening screws lock it around the barrel nut once it is flush with the upper receiver. It is a direct, no-fuss upgrade for anyone building or re-railing an AR-15.
