• Align with the 1913 rail, slide into place, and tighten the side screw for a secure, stable fit with quick tool-free mounting and removal
• Press the ambidextrous side release button to test deploy and fold functionality, verifying the sight locks firmly into place in both stowed and deployed positions

Adjustment Instructions

• Spring-Assisted Flip-Up Operation                                                                                                                                Press the side release button to deploy the sight automatically. It locks firmly in place when raised and stays  securely folded when stored, allowing fast one-handed operation
• Precise Zeroing Adjustment                                                                                                                                    Independent windage and elevation adjustment knobs provide crisp detent click feedback for smooth, accurate,  and stable calibration

Maintenance Guidelines

• Wipe off surface dust and loose sand gently with a soft cloth. Avoid using hard objects that may scratch the anodized surface layer
• Apply a small amount of lubricant to the pivot and spring area periodically to keep the flip-up action smooth and free from sticking
• After outdoor use in rain, sand, or dusty environments, wipe off surface moisture, dust, and debris. For long-term storage, keep the sight in a dry, cool place and avoid impacts, heavy pressure, or scratches to the body
• Do not disassemble the internal spring or adjustment structure unless performed by qualified personnel. Improper disassembly may affect the original locking precision and adjustment detent feedback
