5KU B-33 AK RIS Aluminum Dust Cover - Black

B-33 RIS Aluminum Dust Cover for AK

Looking for a durable and solid RIS mount for your AK rifle that allows mounting a red dot or rifle scope directly above the barrel? Need to replace your standard dust cover with a version that features a full-length 20 mm RIS rail without affecting the gun’s balance? The B-33 aluminum cover from 5KU is a modernized upgrade that replaces the original dust cover and adds a rigid top rail for mounting optics. The entire body is CNC-machined from high-grade aluminum, ensuring excellent fit, precision, and strength while keeping the weight low. The integrated 20 mm Picatinny rail allows installation of various optics directly over the receiver for optimal alignment. At just 230 g, it maintains a balanced feel and minimal added mass. Note that installation requires the 5KU B-10M lower handguard to ensure proper fitment and secure attachment on most AK AEG replicas, including LCT models.
