The Reptilia ROF-90 34mm ACRO mount is a quick-transition optic adapter that turns your magnified scope setup into a dual-optic rig without the permanent commitment. If you run a precision rifle with a fixed or variable magnified optic, the ROF-90 lets you bolt an Aimpoint ACRO P1/P2 or Steiner MPS reflex sight to the side of your scope at 90 degrees—giving you a fast, close-range aiming option while keeping your primary magnified glass ready for distance work. Originally designed for operators who needed passive aiming with night vision and quick target transitions, it's equally useful for hunters working mixed-distance terrain or shooters who want subsonic-load flexibility without changing zero on their primary optic.
The ROF-90 mounts directly into Reptilia AUS mounts or Geissele Super Precision 34mm rings, making installation straightforward if you're already running compatible hardware. Machined from 7075-T6 billet aluminum and treated to MIL-STD Type III hardcoat anodize, it's built tough enough for duty use. At 35 grams, it won't bloat your rifle's weight budget, and the clean design keeps both sight pictures unobstructed. The engineering pays attention to clearance—the close-range optic sits close enough to the centerline for a compact sight radius without shadowing your primary scope's view.
This is the black anodize version, made in the USA. Whether you're setting up a subsonic-capable rifle, adding a no-mag backup to a long-range build, or building a multipurpose field rig, the ROF-90 gives you that flexibility without compromise.

Yes. The ROF-90 allows you to zero the reflex sight for subsonic loads like 300 AAC Blackout while keeping your magnified optic zeroed for supersonic ammunition, giving you flexibility with different cartridge types on the same rifle.
