ANGSTADT SUPP SERIES 14.8" M-LOK

The Angstadt Arms Supp Series 14.8" M-LOK handguard brings modern ergonomics and modularity to your AR build without the installation headaches. This 14.8-inch rail solves a real problem: it mounts to your upper receiver with zero timing, shimming, or fitment guesswork. Whether you're running a forged or billet upper, or shooting .223/5.56 or 9mm, this handguard is ready to go straight out of the box—no gunsmith required.

The design centers on practical mounting flexibility. You get M-LOK slots at 3, 6, and 9 o'clock positions, plus dedicated 45-degree angle surfaces for accessories that need angled mounting. A continuous mil-spec 1913 Picatinny rail runs the length of the top, complete with lightening cuts to keep weight reasonable. Two QD swivel attachment points round out the mounting ecosystem, making it easy to sling your rifle or add quick-detach gear. At 14.5 ounces with hardware included, the weight penalty is minimal for the versatility you gain.

Built from mil-spec hard coat anodized aluminum in black with laser-engraved Angstadt markings, this handguard handles hard use and keeps its finish through field seasons. The 1.7-inch internal diameter accommodates standard AR barrels without clearance drama. All necessary mounting hardware ships with the handguard, so you're not hunting through your spare parts bin before you can install it.
