This complete upper is Left-Handed and 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.
