I have designed a tool to remove and install the battery cap to the SRO without causing any damage to the cap or taking a chance for a screw driver to slip and damage your optic. I used the guys on the Benelli forum as my first batch testers and they are all very pleased. The tools are metal and very strong. They sell for $25 shipped. My new order has 20 units available. I take PayPal, Cash App or Facebook Pay. I will even take a USPS money order in the mail. PM me if interested.
