ANGSTADT SUPP SERIES 9.3" M-LOK

The Angstadt SUPP Series 9.3" M-LOK handguard is a modern free-floating rail system engineered for shooters who want serious modularity without the installation headaches. Unlike older designs, this handguard requires no timing, shimming, or gunsmithing—drop it on a forged or billet upper receiver and get to shooting. Built around a full-length top Picatinny rail with integral lightening cuts, the SUPP Series gives you multiple ways to mount optics, lights, foregrips, and other tactical gear.

The 1.7" internal diameter and 9.3" length make this a natural fit for mid-length build platforms, whether you're running .223/5.56, 9mm, or other AR calibers (except .308). M-LOK slots run the length of the handguard—on the standard 3, 6, and 9 o'clock positions plus 45-degree angles—so you have the attachment flexibility modern shooters expect. Two QD swivel mounting points let you sling it up quickly, and the mil-spec hard coat black anodize finish is built to take a beating on the range or in the field.

At 11 ounces with all hardware included, the SUPP Series strikes a practical balance: light enough not to throw off your handling, substantial enough to feel like real kit. Angstadt's laser engraving adds a professional touch. This is a no-fuss, do-it-yourself handguard that pairs well with short-barrel builds and anyone tired of wrestle with shims and timing.
