Angstadt Arms Ultra Light Handguard Features The Angstadt Arms Ultra Light Handguard is purpose built for compact pistol caliber AR builds with a 4 length and a slim 1.375 inside diameter that keeps the overall package as small as possible. That narrow profile still leaves enough internal clearance to shroud a suppressor up to 1.40 in diameter when the handguard is paired with an exact length 4.5 barrel letting builders run a can without adding unnecessary bulk. An M-LOK mounting system along the sides accepts lights grips and other accessories while a Picatinny rail up top provides a mounting surface for optics or sights. The design works across both 5.56/.223 and 9mm chamberings giving it flexibility across different AR-15 pistol builds. Machined from aluminum and finished in a durable black anodized coating the handguard resists wear and corrosion through heavy use on the range or in the field. It mounts as a free floating forend which keeps the barrel isolated from handguard pressure for more consistent accuracy. Installation requires no timing and uses a standard wrench so builders can get the handguard fitted without specialty tools. All necessary mounting hardware ships with the unit making it a straightforward upgrade for anyone assembling a dedicated small-frame AR-15 pistol.
