Polymer80 P80 Thr/Flu Brl N/Sght 15Rd

Overview

If you are building a custom pistol from the ground up, the Polymer80 p80 thr/flu brl n/sght 15rd is a component that deserves a close look. This part combines a threaded and fluted barrel with a set of iron night sights, plus a 15-round magazine, giving you a solid foundation for a reliable range or defensive build. Polymer80 has a reputation for making parts that fit together with minimal fuss, and this package is no exception. Whether you are finishing a frame you have been working on or upgrading an existing slide, this setup is designed to get you on target quickly.

The p80 thr/flu brl n/sght 15rd is built around the idea of practicality. The threaded barrel allows for muzzle devices if you want them, while the fluting reduces overall weight without sacrificing barrel integrity. The included night sights are tritium-based, meaning they will glow in low-light conditions without needing a battery. This is not a showpiece; it is a working part for someone who expects their firearm to perform when it matters.

Features & Specs

Here is what you get with the Polymer80 p80 thr/flu brl n/sght 15rd, broken down by the key components that matter most to a builder.

• Threaded and fluted barrel: The threading is 1/2×28, standard for most pistol compensators and suppressors. Fluting helps dissipate heat and shaves off a few ounces compared to a solid barrel profile.
• Night sights: Three-dot tritium sights that are drift-adjustable for windage. They are installed and ready to use out of the box, saving you a trip to a gunsmith for sight pressing.
• 15-round magazine: Magazine is compatible with standard double-stack frames and uses a steel body with a polymer basepad for durability and smooth reloads.

This p80 thr/flu brl n/sght 15rd package is a drop-in fit for most Polymer80-compatible slides and frames. The barrel is made from 416R stainless steel with a black nitride finish for corrosion resistance. The fluting runs the length of the barrel, and the crown is recessed to protect the rifling.

Who It’s For

This package is for the builder who wants a complete barrel and sight solution without piecemealing parts from three different vendors. If you are assembling a Polymer80 frame and need a threaded barrel for a suppressor or compensator, the p80 thr/flu brl n/sght 15rd covers that requirement. The night sights make it a strong choice for anyone who carries or uses their pistol in variable lighting, such as early morning or evening training sessions. It also appeals to shooters who prefer the reduced muzzle flip that a threaded barrel plus compensator can offer, though you will need to source the compensator separately. This is not a competition-only part; it is equally at home on a home defense pistol or a weekend range toy.

If you are new to building, this package simplifies the process by giving you a barrel and sights that are matched to work together. The 15-round magazine is a bonus that gets you shooting right away, provided you are in a state where standard capacity magazines are legal.
