The Aim Sports MTK13H308 is a 13.5-inch free-float handguard built for .308 AR-10 rifles running the DPMS high-profile pattern. It replaces your factory drop-in guard with a slimmer, more capable setup that keeps everything off the barrel for better consistency downrange. The tube is machined from 6061-T6 aluminum with a black hard-coat anodized finish, so it shrugs off handling and holds up to heat during longer strings.
You get seven rows of KeyMod slots running the length of the guard, which means you can hang a vertical grip, bipod, light, laser, sling mount, or short rail sections right where you want them. Up top there is a continuous 1913 Picatinny rail that lines up with your upper for mounting optics, a red dot, or backup irons across the full sight radius. Owners consistently mention how light and comfortable the guard feels in hand, and the KeyMod cuts come clean without sharp edges.
This is a free-float design, so it threads onto its own steel barrel nut rather than clamping around the factory setup. Aim Sports includes proprietary steel mounting hardware and a built-in anti-rotation index that keeps the top rail aligned with your receiver. A common tip from folks who have installed one: seat the gas tube anti-rotation key first, then slide the handguard into place before running the clamping bolts. You'll want a barrel nut wrench that matches the Aim Sports nut pattern, since one is not included in the box.
The big thing to nail down before ordering is your upper receiver profile. This is the HIGH profile version, so it pairs with DPMS-style high-profile uppers and clones built to the same barrel nut and dimensions. It will not fit Armalite-pattern rifles, which use a different thread setup. If you're building or upgrading a DPMS-spec .308 and want real modularity at a sensible price, this one earns its spot.
This is the high-profile version, so it's built for DPMS-style high-profile AR-10 and LR-308 uppers along with clones made to the same barrel nut and dimensions. It will not fit Armalite-pattern rifles, which use a different thread count. Always confirm whether your upper is high or low profile before ordering, since that's the number one fitment mistake people make.
Yes, the MTK13H308 ships with its own steel barrel nut and the proprietary steel clamping hardware needed to mount it. What it does not include is a barrel nut wrench, so you'll want one that matches the Aim Sports nut pattern to torque it down properly.
The seven rows of KeyMod slots let you attach foregrips, bipods, lights, lasers, sling mounts, hand stops, and short rail sections directly to the guard. The continuous 1913 top rail handles optics, red dots, magnifiers, and backup iron sights. That combination covers just about any setup you'd want on a .308 rifle.
Installation is straightforward for anyone comfortable working on an AR platform. You torque down the steel barrel nut, seat the anti-rotation gas tube key, slide the handguard on, and run the clamping bolts. A helpful trick is fitting the anti-rotation key before sliding the guard fully into place so the top rail lines up cleanly with your receiver.
