Angstadt Arms Ultra Light M-LOK Handguard, 5.50 Inch AR-15

The Angstadt Arms Ultra Light Handguard (brand part number AA055HGMLT) is a 5.50 inch free-float M-LOK handguard machined from aluminum with a black anodized finish, built for an aggressively slim AR-15 build. Its 1.375 inch inside diameter is tight enough to keep the profile compact while still allowing a suppressor up to 1.40 inches in diameter to tuck inside the handguard when paired with an exact-length 6 inch barrel. It works with both .223/5.56 and 9mm caliber uppers, installs with a standard wrench with no timing required, and ships complete with mounting hardware. Note that it is not compatible with .308/M5 platform uppers.
