The RetroArms CNC AK Cube is a premium support piece designed to support the Hop-Up chambers of AK-style airsoft replicas. This durable, CNC-machined part improves chamber alignment, prevents tilting, and makes loading magazines easier – especially in fast-paced situations.
The RetroArms AK Cube is made from EN AW 7075 aircraft grade aluminum, which combines the strength of steel with the lightness of aluminum. The block is precision CNC machined and anodized with a 5 micron (0.005 mm) protective finish.
The original plastic internal support part of AK frames does not support the Hop-Up chamber position, which can lead to misalignment and uneven feeding. The RetroArms support block keeps the Hop-Up chamber stable and straight inside the frame, preventing it from tilting and ensuring smooth operation.
In addition, the cube includes an integrated guide plate that makes it easier to insert the magazine into the frame at the right angle, prevents magazine damage, and allows for quick magazine changes without problems.
