The WILLIAMS GUN SIGHT COMPANY Store has the best Gun Sights on the market. The Mossberg 500 Red Green Sight (66370) is a top-tier sight that stands out for its brightness, build quality, and customer support. Installation is a breeze, too, so you'll be able to get your gun sight up and running in no time. Plus, it's available in black and one size fits all. Get yours today!
Joseph Lee: These are made specifically for Mossberg rifled slug barrels. And they work.
The pic in the ad is not the actual part 66370. That's why there's some confusion. Again, 66370 is specifically for Mossberg slug barrels that come with ramps from the factory, not the ones with the cantilever picatinny rail nor do they fit smooth bores. The front is dovetailed but uses a set screw instead of being pressed in and the rear fits WGO/WGOS mounts. If you don't have the specific barrels these sights are made for, you will need the mounts and gunsmith skills/tools as well.
This is the best price I've seen and these sights are hard to find. I recommend. The front sight is like a red beacon in low light and does not wash out when you're facing the sun. These sights even pick up light from a flashlight when you're hunting critters after dark!
I would prefer a fatter front sight. These are small and more precision rifle than slug gun. But if you have a sub MOA slug barrel, they'll be awesome. The front sight is bright so it's not really an issue, just a personal preference.

Jim Bob Oakley: These are SO COOL! Easy to install on my Mossberg. Bright whenever there is light for them to gather and speeds your targeting. Of no use in the dark at all, not glow in the dark or anything like that. Works in bright sun fantastically.

VitaminB6: These sights greatly improved target acquisition over the stock sights. I highly recommend them. They were easy to install and to adjust after installation.

Paul A Vetrone: Product arrived exactly as described, packaged well. Installation was a breeze. Front sight blade fit snugly in the dovetail without any fitting required, and is held in place by set screw (Mossberg factory item). The rear sight was a simple remove and replace operation. I like the sight picture and the overall appearance of the firesight (black parts) vs the factory fiber optic (which is a clear sight with the fiber optic filament installed). The factory sight is a bit puzzling as both are Williams Gun sight items. Not sure why the factory item is different than the FireSight but I'm glad I got the firesight.
