Was doing some more browsing on Chisel Machining website & found something for the A300 Patrol.
https://chiselmachining.com/product/a3coptic/



Finally, an optic rail for the A300 that allows you to co-witness a Red Dot Sight (RDS), while still being able to retail you iron sights as a back-up / co-witness.
Other sight rails either hide your iron sights completely, or change your point of impact when using the irons. This system takes advantage of the rear receiver slope, allowing a lower positioning of the RDS.
Simple installation that re-uses your stock A300 rear-sight. Only available for A300 currently. 1301 version coming soon.
Currently only available in RMR flavor.
RDS (and other accessories seen) not included unless purchased in combo.
