Question: Is the tritium in the front and rear or just front?
Document: At first I thought it was my alarm clock but it was the tritium glow from the front sight of the shotgun leaning against the wall. I had read that some complained that the rear sights are not bright enough. I can tell you, in the dead of night, when I imagine these sights will come into play; they will be more than adequate. I picked up the shotgun and held it in firing position and was amazed how bright the front and rear sight were and how well they lined up.
If it had this, it would be the perfect product as the front sight is very high and seems susceptible to damage.The tritium is excellent.
solid built,and the tritium glows like crazy. i would get the front sight brazed on though. the finish is a parkerized type.
No fault of the manufacturer, its all mine. The lesson here is, "go slow". Get the job right the first time. Go slow! Anyway, I had to re-drill the hole and got the rear sight installed. Not a perfect job but it will suffice and I see no issues down the line.The front sight was rather easy.
This product is excellent but you need good metal working skills and a drill press if you want to do a professional job mounting the rear sight. It has no directions on how to mount it. Use extra caution when installing as the rear screw for the rear sight has to be very close to a solid block of steel in the receiver. Proper mounting and you can miss this thick block.The front requires grinding off the bead.
The tritium inserts are not nearly as bright as those on my trijicon handgun sights. Even in total darkness I can barely make them out. Other than that they are pretty decent sights for a shotgun. I don't think I would go with them again though.
I got these for my Police Magnum and easily zeroed them at 50 yards. When zeroing them you should adjust your elevation first, then your windage because of the way the rear sight is held in place. Absolutely love them and would definitely buy another set if I had another 870.
There's a common misconception that shotguns are not meant for long-range shooting. As long as slugs are chambered in a shotgun, they are accurate well past 75 yards. These sights are perfect for both short-range and long-range tactical shooting. As an added bonus, they're also 24/7 tritium night sights.
First off, I recommend you get a shotgun with this already installed if you don't already have the gun. The receiver needs to be drilled and tapped to mount the rear ghost ring. I had a hard time finding a gun smith who would do this. If you have someone who will do this (and you trust them) it is a great addition to the 870. I much prefer this to rifled or bead sight.
Sights arrived packaged as "Scattergun Trijicon Night Sights".They appear to be very well made out of solid steel. I am very impressed with the quality of these sights and feel they will stand up to mild abuse.I had some difficulty installing these sights. They did not come with installation instructions but I did find them on the web. I installed them myself and halfway through tapping the first hole for the rear peep sight the drill tap snapped off.
Answer: yes
