Product DescriptionThe Angstadt Arms Ultra Light 5.5" free-float handguard is built for compact AR-15 setups where low weight and a slim, aggressive profile matter. Its M-LOK mounting interface at the 3, 6, and 9 o'clock positions keeps accessory mounting streamlined, while the continuous top Mil-Spec 1913 Picatinny rail provides a solid mounting surface for sights and accessories. The ultra-slim 1.375" inside diameter design also supports suppressor-tuck builds (up to 1.40" diameter or smaller) when paired with an exact-length 6" barrel. Designed to work with both forged and billet upper receivers, it installs without timing using a standard wrench.Product Highlights Ultra-light 5.5" free-float handguard for AR-15 platform builds (approximately 5.3 oz) M-LOK accessory mounting at 3, 6, and 9 o'clock for a clean, modular setup Continuous top Mil-Spec 1913 Picatinny rail with lightening cut Slim 1.375" inside diameter to help enable suppressor tuck (up to 1.40" diameter or smaller) No timing required; installs with a standard wrench and includes mounting hardwareSpecs Brand: Angstadt Arms Manufacturer Part Number: AA055HGMLT UPC: 853427007516 Type: Handguard (Free-Float) Length: 5.5 in Mount Interface: M-LOK (3, 6, 9 o'clock positions) Top Rail: Mil-Spec 1913 Picatinny (continuous) Inside Diameter: 1.375 in (supports suppressor tuck up to 1.40 in diameter or smaller) Compatibility: AR-15 platform; forged and billet upper receivers; .223/5.56 and 9mm configurations Color/Finish: Black (anodized/hard coat anodized) Material: Aluminum Weight: 5.3 oz Included Accessories: HardwareDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
