The Vortex Red Dot Cantilever 30 mm Ring with a 1-inch offset is a purpose-built mounting accessory that provides extra rail space and optimal positioning for your red dot or 30 mm optic on a Picatinny rail-equipped rifle, particularly on AR-style platforms. By offsetting the optic about one inch forward from the rail, it helps clear rear back-up iron sights (BUIS) or a magnifier while ensuring proper eye relief and comfortable shooting posture, and it works with most 30 mm red dot sights.

The mount is machined from durable aluminum with a matte black finish and is designed to offer a secure and stable attachment that maintains alignment under recoil. Depending on the specific model chosen, you can get either an absolute co-witness height (approximately 1.46 inches centerline above the rail) or a lower 1/3 co-witness height (around 1.57 inches), letting you match your sight height to your preferred iron-sight setup and shooting style. The cantilever design balances forward offset with solid clamping strength, making it a practical choice for tactical, range, or hunting use.

Note: Provides lower 1/3 co-witness mounting height of 40 mm. Will work with most 30 mm red dot sights.
