Maxim Defense MD:15 Free Float AR-15 Handguard - ARCA / M-LOK - 17.2"

The Maxim Defense MD:15 M-LOK AR-15 ARCA Free Float Handguard at 17.2" is the longest ARCA-equipped option in the MD:15 AR-15 handguard line, providing the maximum integrated ARCA Swiss coverage for extended-barrel rifle configurations that demand the most stable possible support interface. Built for 20" and longer barrel builds where ARCA interface span is a primary specification, this free float handguard delivers the full length of continuous clamping surface the MD:15 system offers.

The MD:15 M-LOK AR-15 ARCA Free Float Handguard is a free float handguard for AR-15 and MD:15 platforms incorporating a full-length integrated ARCA Swiss bottom rail, M-LOK compatibility, and a Picatinny top rail across the longest configuration available in the MD:15 handguard family.

At 17.2", the integrated ARCA Swiss bottom rail runs the length of the handguard, providing an uninterrupted clamping surface for tripod heads, ARCA-compatible bipods, and support bags at any position. This length allows support point adjustments across a large range without losing ARCA interface coverage. Free float construction at this length is essential for precision applications, maintaining barrel independence from the handguard regardless of what support forces are applied.

Precision-fit for the MD:15 platform and compatible with standard AR-15 receivers. Designed for 20" and longer extended-barrel rifle configurations. Outer diameter: 1.6". Inner diameter: 1.32". Machined aluminum with a hard coat anodized finish.

The maximum-length ARCA option for extended-barrel AR-15 precision builds where the full ARCA Swiss interface span of the MD:15 system is needed for tripod and support system stability.

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