The MX-1 stock and stabilizer brace systems are designed for rigid security when extended and compact storage when folded. Because the hinge utilizes a vertical locking detent to prevent accidental collapse during live fire, you must articulate the joint correctly to fold it.

Follow this guide to ensure smooth functionality and prevent damage to the locking mechanism.

📁 How to Close (Fold) the Stock

🛑 Crucial Rule: The stock cannot be turned or folded by applying lateral (sideways) force alone. To unlock the hinge, you must push it upwards before attempting to rotate it.

Method 1: The One-Handed Pinch (Recommended)

1. Place your thumb on top of the chassis spine, near the charging handle channel.

2. Grip the underside of the stock joint tightly with your remaining fingers.

3. Squeeze your hand to push the stock vertically upwards, clearing the locking lug.

4. Once lifted, rotate the stock inward toward the side of the chassis. It will now securely rest in the folded position.

Method 2: The Base Pin Push (Alternative)

1. Press your thumb directly against the bottom face of the hinge pin.

2. Push firmly upwards to release the lock, while simultaneously rotating the stock sideways to swing it into its stowed position.

🚀 How to Open (Deploy) the Stock

1. Grasp the rear of the folded stock or brace.

2. Pull the assembly outward and back with a firm, continuous motion.

3. The stock will swing completely open and automatically snap downward into its locked, extended position. Always double-check that the joint is entirely rigid before aiming or firing.
