Trijicon AC32066: 45° SRO / RMR Offset Rail
Perfect for that situation where you need the versatility of a magnified optic paired with a Trijicon RMR® or SRO™ red dot sight in close quarters.
This offset rail adapter attaches to the firearm’s Picatinny rail and provides a short Picatinny rail at a 45° offset to mount a red dot sight.
Please note that this is just the rail adapter. In order to mount the Trijicon RMR® or SRO™, you will also need the RM33 Low Mount.
By mounting a red dot at a 45° offset, it allows for an easy transition from the magnified optic by simply rotating the firearm. The low profile of this mount allows you to mount underneath almost any riflescope (such as the Trijicon AccuPoint®) without removing the scope or rings, or in front/behind the optic (such as the Trijicon ACOG® or VCOG®).

Customer Ratings & Reviews
Read this before looking at cheaper ones.
There are numerous offset adapters available, but many of them are ineffective as the turret of the primary scope obstructs the red dot. Out of all of them, the trijicon ac32066 and the Daniel Defense are the only viable options. This adapter is pricey, but it's worth it because it places the sight low enough to clear the turrets, unlike other well-constructed adapters. So, this and the DD are the only worthwhile choices.
Finally, the perfect adapter for my second optic sight - I love it, and use nothing else
After trying numerous adapters for my Burris Fastfire III, I finally found the one I will stick with - this one. I desired the sight to be directly in line with the barrel and level while the rifle was canted. This adapter is the only one that accomplishes that task. All others I tried resulted in misaligned optics, either not level above the barrel or parallel to the side. This mount is well-constructed and solid, and has improved my shooting accuracy.
The perfect angle for your offset red dot
After trying other offset mounts, I decided to invest in the trijicon ac32066 due to its low profile. It's one of the few mounts that drops low enough to align the red dot with the barrel, and low enough to clear the adjustment knobs on my top-mounted scope.
Beware where you install this, it may cause malfunctions on an AR.
This is a typical high-quality Trijicon product, though expensive. It corrects the alignment of the RMR with the barrel center line. Most offset adapters are not meant for aiming devices, so it doesn't matter much if your flashlight is misaligned with the bore. I purchased this offset rail adapter because my Trijicon ACOG M150 scope takes up most of the only rail space I have on my Colt LE M4 carbine. Although the ACOG model is designed to allow it, I don't like mounting an RMR or other reflex sight above the scope because it places it too high on the rifle and increases the risk of damage or getting caught on objects. The Trijicon offset mount correctly locates the reflex sight relative to the barrel for easier adjustments and improved accuracy. It's also positioned in a more convenient location. The generic offset mount put the RML at an awkward angle to the barrel, making zeroing difficult in all directions. With the Trijicon mount, the reflex sight is located closer to the barrel and perpendicular to it, allowing for better accuracy."
great value, quality product.
I purchased offset rail to mount a light on my AR, it is a quality made product and everything is mounted uptight and firm and most importantly stayed that way after shooting a few hundred rounds through the rifle. I would highly recommend it.
I bought this trijicon rmr offset mount for use on my AR308. It holds a SeeAll open sight that functions as backup sights for my magnified scope when hunting in the field and playing on the range. This mount cleared my traditional rifle scope and has held zero after lots of hard field use with full power .308 Winchester.
trijicon rmr offset mount
This worked flawlessly on my ar build it even mounted under the scope
Trijicon rmr offset is really nice
I wasn't sure at first if I could fit these on a new rifle built for sport with my other optics installed. The iron sights work great. A lot faster than flipping my magnifier out of the way. Bring on the zombies!
