P80 Thr/Flu Brl N/Sght 15Rd

Overview

If you are building out a custom frame or finishing a Polymer80 project, the P80 Thr/Flu Brl N/Sght 15rd is a solid choice for a complete slide assembly. This unit brings together a threaded barrel, a set of steel night sights, and a 15-round magazine compatibility in one factory-assembled package. Instead of hunting down individual parts and hoping they fit together, this assembly is built to drop onto your P80 frame with minimal fuss. The “Thr/Flu” designation refers to the threaded barrel with a flush-cut crown, and the barrel is designed to accept standard muzzle devices. The night sights are tritium inserts housed in steel dovetails, giving you low-light visibility without the bulk of an optic. This is a direct replacement or upgrade for compact builds that need a reliable, ready-to-run slide and barrel combo.

Features & Specs

The P80 Thr/Flu Brl N/Sght 15rd is manufactured by Polymer80, a name you know if you have spent any time in the DIY pistol space. This is a factory-assembled slide and barrel set, not a collection of loose parts. Here is what you are getting out of the box:

• Threaded barrel with a 1/2×28 thread pattern, flush-cut crown, and a black nitride finish for corrosion resistance and reduced wear.
• Steel front and rear night sights with tritium inserts, drift-adjustable for windage, and a standard white outline rear for daytime use.
• Designed to work with compact frames and 15-round magazines, the slide is machined from 416 stainless steel with a black nitride coating.

The barrel length is 4.02 inches, and the overall slide length is standard for compact builds. The P80 Thr/Flu Brl N/Sght 15rd includes the recoil spring assembly and the extractor, so it is truly a slide completion kit. The threaded barrel gives you the option to add a compensator or suppressor later, and the night sights mean you are not stuck with plastic or painted dots. This is a functional, no-nonsense setup for someone who wants a complete upper that works from the first time you rack it.

Who It Is For

This product is aimed at the builder who wants a complete slide assembly without the guesswork. If you have a Polymer80 compact frame or a similar compatible lower, and you want a threaded barrel and night sights in one package, the P80 Thr/Flu Brl N/Sght 15rd fits that need. It is also a good option for someone who wants to upgrade an existing compact pistol with a threaded barrel and better sights without buying two separate items and hoping they work together. The 15-round magazine compatibility means it pairs well with standard capacity magazines, and the threaded barrel opens up the option for suppressors or compensators if you are into that. This is not a competition race gun part, and it is not a lightweight carry piece. It is a solid, middle-of-the-road slide assembly for a general-purpose or range-use build.
