Description
When the light drops, standard black iron sights basically disappear. Trijicon's Bright & Tough Night Sights fix that with self-luminous tritium lamps that glow on their own, no batteries and no charging needed. The green front dot pairs with an orange rear on this particular set, which gives your eye two clearly different reference points instead of three identical dots trying to blend together. Trijicon states this three-dot design can boost night-fire accuracy by up to five times over conventional iron sights, and they do it with the same instinctive speed you'd expect in daylight.
What Makes These Trijicon Night Sights Hold Up
The toughness is not just a marketing word here. Each tritium lamp sits inside an aluminum cylinder and rests on a silicone rubber cushion, so hard recoil and impacts get absorbed instead of transferred straight into the lamp. Every lamp is also capped with a sapphire jewel that spreads the glow evenly while shielding the tritium from solvents and punctures. It's the same combat-proven build Trijicon has trusted with law enforcement and military users for years.
Fitting the Orange Rear Sight Set to Your AR
This set is made for mil-spec AR-15 and M16 iron sights, meaning fixed triangle front sight bases and carry-handle or A2-style rear sights. It replaces your existing front post and rear aperture, and the CP25F-TOOL installation tool comes in the box to help you get it done. Trijicon does recommend professional installation, so if you're not comfortable working on your sight base, a good gunsmith can knock it out quickly.
Why the Green and Orange Combo Works
A lot of folks like running two different lamp colors because it makes lining up front-to-rear faster in the dark. The green front dot naturally reads brightest to your eye since it sits farther out, while the orange rear gives you a distinct anchor without washing out the front. The green lamps carry a 12-year warranty and the orange rear carries a 5-year warranty, both from the date of manufacture, so you get plenty of glow life out of this set.

Frequently Asked Questions
Will these Trijicon night sights fit my AR-15?
They're designed for mil-spec AR-15 and M16 iron sights, which covers fixed triangle front sight bases and carry-handle or A2-style rear sights. If your rifle runs standard mil-spec sights, this set will drop right in as a replacement. If you have a proprietary or non-standard sight setup, check the specifics of your rear aperture and front post before ordering.
Do the tritium sights need batteries?
No. The Bright & Tough Night Sights use self-luminous tritium lamps that glow on their own with no batteries, no switches, and no charging. They're always on and ready, which is exactly why this style of sight is so popular for low-light and defensive use.
Can I install the AR-15 night sights myself?
The set comes with the CP25F-TOOL installation tool to help you swap the front post and rear aperture. Trijicon recommends professional installation, so if you aren't comfortable working on your front sight base a gunsmith can handle it quickly. Many buyers report the install is straightforward once you have the right tool in hand.
How long will the tritium lamps stay bright?
The green front lamps carry a 12-year warranty and the orange rear lamp carries a 5-year warranty, both measured from the date of manufacture. Tritium fades gradually over time rather than shutting off all at once, so you'll get years of usable glow out of the set.
