Red dot mounts secure your optic to the firearm and directly affect zero retention, sight picture, and how easily you can co-witness with iron sights.
Here’s what to look at before picking the right mount:
Purchase red dot mounts online or visit our gun shop in St. Clair Shores, Michigan to confirm fitment in person before buying. ICB Firearms also serves customers from nearby cities including Macomb, Clinton Township, Grosse Pointe, Warren, and Royal Oak.
Red dot mounts themselves are not regulated as firearms, though accessories ordered alongside firearms follow federal guidelines and applicable Michigan requirements, which typically involve shipment to a licensed dealer and completion of a background check prior to pickup. Shipping timelines vary by product, so review checkout information carefully before placing your order.
Installation practices, torque specifications, and storage responsibilities may differ based on circumstances. Contact the shop directly for clarification on product compatibility, accepted identification, and current store policies.
A red dot mount is the hardware that attaches a red dot optic to a firearm. It positions the optic at the correct height and angle for proper sight alignment.
Absolute co-witness aligns the red dot directly with iron sights, while lower 1/3 co-witness places the dot above the irons in the bottom third of the sight picture. Lower 1/3 is often preferred for a less cluttered view.
No, mounts are designed around specific optic footprints and firearm platforms. Always check that the mount matches both your red dot’s mounting pattern and your firearm’s rail or slide cut.
A footprint refers to the screw and pin pattern on the bottom of the optic that interfaces with the mount. Common footprints include RMR, Docter, and ACRO, each requiring a matching mount or adapter plate.
Quick detach mounts allow fast removal without tools, which is useful for swapping optics or accessing backup sights. Most quality QD mounts return to zero reliably when reattached.
Clean the mounting surface, position the mount correctly, then torque the screws to the manufacturer’s specifications. Many shooters apply thread locker to keep screws secure under recoil.
Some pistols come optics ready with factory cuts that accept specific footprints. Older or non-cut slides typically require milling or an adapter plate to mount a red dot.
Lower 1/3 co-witness mounts at around 1.93 inches are popular for AR-15 platforms because they offer a clearer sight picture and comfortable head position. Absolute co-witness mounts are also widely used.
