This complete upper includes our Slimline Handguard. The slimline line of handguards have a unqiue milling profile, designed to maximize grip ergonimics and minimize weight while still providing plenty of real-estate to accommodate any attachment needs the end user may have. Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
NOTE: This part features a colored anodized finish. These finishes are held to different aesthetic standards than parts finished in black anodizing or Cerakote. For more information on colored anodizing visit our Knowledge Center.
