Check out what Reptilia Corp has to say about their latest product:
The ROF-90 adds a mounting point at 90º (12:00) for a Trijicon RMR to provide for quick transition to a non-magnified optic for close-range target engagement. Additionally it the RMR can be zeroed for use with use with subsonic cartridges such as 300 AAC Blackout, while allocating the magnified optic for use with supersonic ammunition.
The 34mm ROF-90 for RMR is immediately available in hard anodized, Black and Flat Dark Earth!
Like all Reptilia products, the 34mm ROF-90 is 100% made in the USA and carries a full lifetime warranty against manufacturer defects. Additional optic configurations coming soon!
