- Specialized Fitment: Fits into the battery cap slot of Trijicon MRO, MRO Patrol, and MRO HD.

- Scratch Free: 3D-printed tool reduces the likelihood of scratching your optic compared to a coin, screwdriver, or other metal-on-metal contact. I have yet to scratch my battery cap, though your results could in theory vary.

- Hand-Turn Version: Remove the battery cap by turning this tool with your hand. A hex bit version for a screwdriver is also available.

- Usage Notes: Ensure you push the tool into the battery cap while you twist it. When re-tightening, go until it is snug and then stop. This is a plastic tool, and is not meant to tighten it like you'd tire a tire lug nut.

- Original, Innovative Design: 1000+ products designed and 3D printed in the heart of America in St Louis, Missouri by Hammy3DPrints.
