Trijicon SRO Battery Tool — Black
Stonebridge Gunworks · SRO Accessory
The battery cap on a Trijicon SRO is easy to cross-thread and easy to chew up — and it always seems to happen at the range, right after a make-ready sight picture goes sideways. This tool grips the cap properly so it backs out clean and seats straight.

Trijicon SRO battery cap

Black PETG CF
Made in
USA by Stonebridge
Also in bright green and bright orange. Same tool, far easier to find in a range bag — bright green here, and all proceeds from the orange version are donated to the Foundation for Prader-Willi Research.
Why It Exists
ThreadsNo more cross-threading
Square, positive engagement on the cap so you are not starting the threads crooked with cold fingers.
Range readyFor the make-ready surprise
Dead dot on the line is bad enough. Chewing up the cover with a multi-tool makes it worse.
GripReal purchase on the cap
Enough leverage to break a snug cap loose without marring it, and small enough to live in the bag.

How To Use It
Nothing to it — the whole point is doing the job without a multi-tool, a coin, or a screwdriver blade near your optic.
- Seat the tool square on the SRO battery cap.
- Turn counter-clockwise to back the cap out.
- Swap the CR2032, positive side up.
- Start the cap by hand so you know the threads caught.
- Snug it with the tool. Snug, not gorilla-tight.
Fitment
This is for the Trijicon SRO only.
It will not fit an RMR, RCR, or a Holosun — those optics use different battery covers, and several load from the bottom instead of the top.
Cut for the Trijicon SRO battery cap. If you run an SRO, the trainers below are cut for the same optic.
Keep It Where It Helps
Keep it in the range bag with a spare CR2032 taped to it. That is the whole trick — the tool is only useful if it is with you when the dot dies.

Frequently Asked Questions
Will this fit my RMR, RCR, or Holosun?
No. This tool is shaped for the Trijicon SRO battery cap. Other optics use different covers, and some load the battery from the bottom.
What battery does the SRO take?
A CR2032. The tool does not include one — keep a spare in the bag with it.
What is the difference between the black, green, and orange versions?
Function and fit are identical. Black is PETG CF; green and orange are bright PETG so you can actually find them in a range bag. All proceeds from the orange version are donated to the Foundation for Prader-Willi Research.
Do I really need a tool for this?
You need something. Coins, knife blades, and multi-tools are what cross-thread caps and chew up covers. This is shaped for the job and costs less than a battery cap.
