Maxim Defense MD:15 Free Float AR-15 Handguard - ARCA / M-LOK - 10.57"

The Maxim Defense MD:15 M-LOK AR-15 ARCA Free Float Handguard at 10.57" provides mid-length AR-15 builds a longer integrated ARCA Swiss interface than the compact variant, delivering more clamping contact when locked into a tripod head or rested against a shooting bag. Built for mid-length configurations where extended ARCA coverage and M-LOK versatility need to coexist, this free float handguard provides both without external adapters.

The MD:15 M-LOK AR-15 ARCA Free Float Handguard is a free float handguard for AR-15 and MD:15 platforms featuring an integrated ARCA Swiss bottom rail, M-LOK compatibility on primary surfaces, and a continuous Picatinny top rail in a mid-length configuration.

The integrated ARCA Swiss bottom rail provides a continuous clamping surface for tripod heads, ARCA-compatible bipods, and shooting bags across the handguard length. Free float construction ensures that any pressure applied through the ARCA support interface does not transmit to the barrel, maintaining the mechanical independence required for consistent accuracy. M-LOK slots on the remaining surfaces keep light, laser, and accessory options available without the ARCA rail consuming mounting positions. The full-length Picatinny top rail provides a continuous optic mounting surface.

Precision-fit for the MD:15 platform with compatibility for standard mil-spec AR-15 receivers. Length: 10.57". Outer diameter: 1.6". Inner diameter: 1.32".

Free float aluminum construction with a hard coat anodized finish.

A good fit for mid-length AR-15 builds where additional ARCA interface length over a compact variant improves tripod clamping stability without adding full-length handguard bulk.

Maxim Defense backs the MD:15 ARCA Handguard with their manufacturer warranty.
