M4E1 Threaded 16" 5.56 Carbine-Length M4 QPQ No Forward Assist Complete Upper W/ 13.5" Slimline Handguard - OD Green Anodized

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 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.
