Wilson Combat AR-10 M-Lok Handguard 12.6" 6005A-T5 Aluminum Black Hard Coat Anodized

The Wilson Combat AR-10 M-Lok handguard delivers lightweight modularity without compromise on strength or shooter comfort. This 12.6" rail brings the proven T.R.I.M. (Tactical Rail Interface, Modular) design to the AR-10 platform, giving you a free-floating handguard that's precision-machined from 6005A-T5 aircraft aluminum and finished in Mil-Spec hard anodize. If you run an AR-10 and want to mount optics, lights, or other accessories without adding unnecessary weight or bulk, this is a purpose-built upgrade that handles serious use while staying sleek enough for fast, dynamic shooting.

Wilson Combat engineered this rail to be among the lightest and strongest in its class. The three, six, and nine o'clock M-Lok positions let you attach gear exactly where you need it, and the system plays well with the broad range of M-Lok accessories already out there. The barrel nut design is carried over from the original T.R.I.M. rail, so swapping an older version for this new M-Lok handguard is straightforward—no surprises. Installation takes about five minutes with common hand tools, and you can remove or replace it in the field if your setup changes.

Build quality reflects Wilson Combat's attention to detail. The barrel attachment nut is machined from hardened 4130 steel and nitrocarburized to resist heat transfer and rotation. The ergonomic profile keeps your hands comfortable during extended shooting, with no sharp edges or abrasive surfaces. Overall weight comes in at 12.2 oz (13.4 oz with attachments), keeping your rifle balanced and handy. The 1.47" internal diameter works with most low-profile gas blocks, giving you flexibility in your gas system choice.

One note during setup: the hardened screws use a tapered base for a flush fit, so apply a small amount of grease to the tapered shoulder before tightening to prevent galling. Once installed, you have a rock-solid platform that won't shift or rattle under recoil.
