This complete upper receiver features the same tried-and-true construction and aesthetics as our M4E1 Threaded Upper Receivers, without provisions for a forward assist.The slimline line of handguards have a unique milling profile, designed to maximize grip ergonomics and minimize weight while still providing plenty of real-estate to accommodate any attachment needs the end user may have. Our proprietary Aero Taper Lock 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.
