Offset Red Dot Mount | 45 Degree Red Dot Mounts for AR-15
Offset Red Dot Mounts – 45° & 90° Tactical Mounting Solutions
In high-speed tactical environments or competitive shooting scenarios, offset red dot mounts offer a critical edge. These mounts allow shooters to transition instantly from a magnified optic to a secondary red dot sight—without adjusting their cheek weld or primary scope.
At Mounts Plus, we offer a curated selection of top-rated offset red dot mounts, compatible with Trijicon RMR, Aimpoint Micro, Holosun, and more. Whether you're running a 3-Gun rifle, duty AR-15, or LPVO setup, our mounts deliver the reliability and flexibility you need.
🔍 What Is an Offset Red Dot Mount?
An offset red dot mount is a firearm accessory that positions a red dot sight at an angle—usually 45 degrees—relative to your primary optic. This allows quick transitions between long-range magnified optics and close-quarters red dot targeting without removing your eye from the rifle.
Offset mounts are essential for:
-
LPVO + red dot combos
-
Backup sighting systems
-
Dynamic shooting & CQB transitions

🛠 Compatibility & Installation
Offset mounts work with most 1913 Picatinny rails, scope mount top rings, or handguard sections.
They are often optic-specific (RMR, ACRO, T1/T2), so select a mount that matches your red dot’s footprint.
Installation Tips:
-
Torque screws to manufacturer specs (usually 15–25 in-lbs)
-
Confirm optic alignment for true 45° sighting
-
Use thread locker for high-recoil firearms
