Description
When you need a set of backup irons that work as well at 2 a.m. as they do at high noon, the Trijicon Bright & Tough Night Sights for AR-15 and M16 rifles are a proven pick. These are three-dot iron sights using sealed tritium lamps, so they glow on their own without batteries, switches, or any charging up beforehand. Trijicon reports these sights can improve night-fire accuracy by up to five times over plain black iron sights, and they let you aim with the same instinctive speed you're used to during the day.
What Makes the Bright & Tough Set Hold Up
These aren't flimsy. The sight blades are machined from steel rather than cast, which gives them the kind of toughness you want on a hard-use rifle. Each tritium lamp lives inside an aluminum cylinder and gets capped with a sapphire jewel that spreads the light evenly while shielding the lamp from solvents and punctures. On top of that, the lamps ride on silicone rubber cushions built to soak up shock and heavy recoil, so daily range abuse or a knock against the truck door isn't going to rattle them loose.
Green Dots on the AR-15/M16 Night Sights
This version runs green front and green rear dots, which is Trijicon's brightest lamp color and the reason it's the go-to for low-light and no-light work. The front dot carries a white outline ring to help your eye pick it up fast. If you ever want more contrast between front and rear, Trijicon also offers yellow and orange rear options in the CP25 family, but plenty of folks stick with the all-green setup for maximum brightness.
Getting the Trijicon Night Sights Installed
The set ships with the CP25F-TOOL front sight tool, so the front sight goes on without much fuss. The rear takes a bit more work and a small punch to knock out the windage knob retainer pin, and Trijicon recommends professional installation if you're not comfortable working on your own gun. The green tritium lamps are backed by a 12-year warranty from the date of manufacture, giving you plenty of years of steady glow.

Frequently Asked Questions
Do the Trijicon Bright & Tough Night Sights need batteries?
No. These sights are self-illuminating using sealed tritium lamps, so they glow on their own with no batteries, switches, or charging. That means they're always ready the moment you shoulder the rifle in low light.
Will this CP25 set fit my AR-15?
This set is designed for AR-15 and M16 platforms, replacing your standard front and rear iron sights. It's the green front and green rear configuration in Trijicon's CP25 lineup. If you have a non-standard sight setup, it's worth confirming your rifle uses a typical A2-style front sight base and detachable carry-handle-style rear.
How hard are these AR-15 night sights to install?
The front sight is fairly straightforward since the set includes the CP25F-TOOL front sight tool. The rear takes a little more effort and a small punch to drive out the windage knob retainer pin, so if you're not comfortable working on your rifle, professional installation is recommended.
How long will the tritium in these sights stay bright?
Trijicon backs the green tritium lamps with a 12-year warranty from the date of manufacture. Green is the brightest lamp color Trijicon offers, which is why it's the standard choice for serious low-light and no-light use.
