M-LOK mounting and rail design

The M-LOK slot pattern provides a proven interface for tactical attachments while keeping the profile streamlined. At 16 inches, this handguard balances sight radius with maneuverability for mid-length builds. The lightweight construction reduces front-end weight, improving handling characteristics.
