Description

When ambient light disappears, standard black iron sights disappear right along with it. The Trijicon Bright & Tough Night Sights for the AR-15/M16 fix that with a three-dot tritium setup that glows on its own, no batteries and no charging up needed. You get a green front post and two yellow rear dots, a combo built to boost night-fire accuracy and let you pick up your sight picture fast when it counts.

Why the Green Front and Yellow Rear on This CP25Y Set Works

Trijicon builds these with a specific job in mind. Green tritium sits up front because it's the brightest color and pulls your eye straight to the front post, while the yellow rear dots give you clear separation from that front sight so you never confuse the two in the dark. Yellow was chosen for the rear over orange because it runs brighter and lasts longer, which is also why the yellow lamps carry a 12-year warranty from the date of manufacture.

What Makes the Bright & Tough Sights Live Up to the Name

These are built to take a beating. Each tritium lamp sits inside an aluminum cylinder, gets capped with a sapphire jewel to spread the light evenly and shield it from solvents and punctures, then rides on a silicone rubber cushion to soak up shock and heavy recoil. The sight blades are machined from steel rather than cast, so they hold zero and shrug off abuse. Folks who've run these on M4-pattern rifles across years of hard use tend to praise the rock-solid reliability and simple operation.

Fitment and Install Notes for the AR-15/M16 Sights

This set is cut for the Colt AR-15/M16 platform and ships with the CP25F-TOOL front sight adjustment tool. The front post is easy to swap on most builds, and the rear takes a bit more patience. Trijicon recommends professional installation, and pairing the front and rear together gives you the full aiming reference in low light rather than half the picture.

Frequently Asked Questions

Do the Trijicon Bright & Tough night sights need batteries?

No. The illumination comes from tritium, which glows on its own without any batteries, charging, or exposure to light beforehand. That means the sights are always ready in low or no light, and the yellow lamps are warranted for 12 years from the date of manufacture.

Why is the rear yellow instead of green on this CP25Y set?

The green front dot is the brightest and grabs your eye where it matters most, while the yellow rear dots give clear color separation so you don't confuse front and rear in the dark. Trijicon went with yellow over orange for the rear because it runs brighter and lasts longer. It's a setup a lot of people prefer for faster sight alignment.

Will these fit my AR-15?

This set is designed for the Colt AR-15/M16 pattern. The front post swaps onto most standard front sight bases fairly easily, and it comes with the CP25F-TOOL to help with that. The rear takes more effort, and Trijicon recommends professional installation to get everything seated and zeroed correctly.

How tough are these sights really?

Very. Each tritium lamp lives inside an aluminum cylinder, gets a sapphire jewel cap for protection, and sits on a silicone rubber cushion to handle recoil and impact. The blades are machined from solid steel rather than cast, so they hold up to heavy use and keep their zero.
