The Angstadt Arms Ultra Light 4" Free Float Handguard (AA004HGMLT) is purpose-built for compact AR-15 pistol builds that demand both performance and an aggressive, tactical aesthetic. Precision-machined from lightweight aluminum and finished in a durable black anodized coating, this handguard features a very slim 1.375" inner diameter profile that still accommodates sound suppressors up to 1.40" in diameter when paired with a 4.5" barrel. The M-LOK mounting interface at the 3, 6, and 9 o'clock positions provides versatile accessory attachment options, while the uninterrupted Mil-Spec 1913 Picatinny top rail with lightening cuts ensures continuous compatibility with optics and accessories. Two Quick Detach (QD) swivel mounting points allow for convenient sling connections, and the engraved Angstadt Arms logo adds a distinctive finishing touch. Compatible with both .223/5.56x45mm and 9mm calibers, this handguard installs without timing using a standard wrench and is suitable for both forged and billet upper receivers. All necessary hardware is included.
