Polymer80 P80 Thr/Flu Brl N/Sght 15Rd

If you are building a custom pistol platform and need a reliable, drop-in ready component that balances performance with straightforward installation, the Polymer80 P80 Thr/Flu Brl N/Sght 15rd is a solid choice. This part combines a threaded barrel with a flush-fit design, includes night sights, and comes with a 15-round magazine. It is built for shooters who want a ready-to-run slide assembly without the hassle of sourcing individual pieces. Whether you are finishing a frame or upgrading an existing build, this component keeps the process clean and the results consistent.

Overview

The P80 Thr/Flu Brl N/Sght 15rd is a complete slide assembly from Polymer80, designed to pair with their popular frame kits. It features a threaded barrel for suppressor or compensator use, a flush-cut barrel crown, and pre-installed tritium night sights. The assembly also includes a 15-round magazine, making it a practical package for range use or defensive setups. This part is built to standard dimensions and does not require specialized fitting for most compatible frames. It is a straightforward option for builders who want reliable function without overcomplicating the build process.

Features & Specs

This assembly brings together several practical features that matter for both new builders and experienced shooters. The threaded barrel is 1/2×28, a common thread pitch for suppressors and compensators. The night sights use tritium inserts for low-light visibility, and the barrel is machined from 416 stainless steel with a black nitride finish for corrosion resistance. The included 15-round magazine is a standard double-stack design, compatible with most compact frames. Here is a breakdown of what you get:

• Threaded barrel in 1/2×28 with flush-fit crown, black nitride finish, 416 stainless steel construction
• Pre-installed tritium night sights for low-light shooting, dovetail front and rear
• Includes one 15-round magazine, compatible with compact frames and standard base pads

This setup is designed to work with Polymer80 frames and most compatible aftermarket lowers. The slide is pre-assembled with the barrel, recoil spring, and sights, so you can install it directly onto your completed frame with minimal effort. The threaded barrel adds versatility for those who want to run a suppressor or a compensator without changing the barrel later.

The night sights are a practical upgrade over standard white-dot sights. They use tritium vials that glow for years without needing a light source to charge. The slide itself is machined from billet 416 stainless steel and finished with a durable black nitride coating. The overall length is standard for compact slides, and the barrel extends slightly past the slide due to the threading. This is a complete drop-in assembly for anyone building a compact pistol with the P80 Thr/Flu Brl N/Sght 15rd as the core component.

Who It’s For

This assembly is built for the home builder who wants a functional slide and barrel combination without sourcing each part separately. It is ideal for someone completing a Polymer80 frame kit, especially if they plan to use a suppressor or compensator in the future. The included night sights make it a good choice for shooters who want a defensive or carry-oriented build. It also works for experienced builders who want a spare slide assembly with a threaded barrel for range use. If you are looking for a reliable, no-surprises component that fits standard frames, the P80 Thr/Flu Brl N/Sght 15rd is a practical option. It is not a competition race gun part, but it handles well for general shooting and training.
