Description
The Cross Armory Red Dot Optic 3 MOA is a compact open red dot sight with a clean 3 MOA dot and a black finish. It is built to give a pistol or small carbine a fast, simple aiming point that is easier to use than iron sights, especially for shooters whose eyes struggle to focus on a front sight.
Cross Armory Red Dot Optic 3 MOA Overview
Cross Armory catalogs this sight as part CRRDORMSC. A 3 MOA dot covers about three inches at 100 yards and about three quarters of an inch at 25 yards, which is a good balance between speed and precision on a handgun. The compact housing keeps weight and height down, so the sight rides low on a slide and does not snag on clothing as easily as a larger optic.
Footprint Note
The part number and our store title point to an RMSc style optic, but retail listings for this UPC describe it as RMR footprint compatible. Those two patterns are not interchangeable. Before you order, check which cut your slide has. If your slide is cut for one pattern and the sight uses the other, an adapter plate may solve it. Cross Armory has not published a full spec sheet that we could find, so call us with your pistol model and we will help confirm fit.
Why a Red Dot on a Pistol
With iron sights you have to line up a rear notch, a front post and the target, and your eye can only focus on one of them. With a red dot you keep both eyes open, focus on the target and put the dot on it. Most shooters see faster first shots and better follow up shots once they get used to presenting the gun so the dot lands in the window.
Getting Started
Mount the sight with the screws and torque values for your plate or slide, and use a small drop of medium thread locker. After zeroing, practice your draw and presentation in dry fire until the dot appears right away. Backup iron sights that co-witness through the window are a good idea on a carry or duty gun.
Zeroing Tips
Most pistol shooters zero a red dot at 15 to 25 yards. Start close to get on paper, then move back and adjust. Fire groups of three to five shots before each change, and confirm zero with the ammunition you plan to carry.
Battery Care
Replace the battery once a year on a defensive gun, even if the dot still looks fine, and keep a spare in your range bag. Wipe the lens with a soft cloth or lens pen, not a shirt tail, to keep the coatings clean. If the dot seems dim or flickers, check the battery and contacts first.
Ordering and Transfer
When you order a firearm from MAG5 Firearms, we ship it to the licensed dealer you choose. Your dealer completes the ATF Form 4473 and the background check, and may charge a transfer fee. Local buyers can complete the transfer at our shop. Bring a valid ID, and check your state waiting period before you plan a hunt or a range trip.
Safe Storage
Store the firearm unloaded in a locked safe or case, with ammunition kept separately. A cable lock or trigger lock is a good backup, especially in a home with children or visitors. Keep the original box and paperwork, and record the serial number in a safe place in case the gun is ever lost or stolen.
