Overview

Built around a precision-machined barrel, the p80 thr/flu brl n/sght 15rd assembly is intended for use with Polymer80 compact and subcompact frames. The threaded barrel allows for the attachment of muzzle devices such as compensators or suppressors, while the fluted profile reduces overall weight and aids in heat dissipation. The included front and rear night sights provide immediate low-light target acquisition, and the 15-round magazine ensures standard capacity for defensive or range use. This product is a direct fit for P80 G19-compatible builds and requires no additional fitting for the barrel or sight installation.

Features & Specs

• Threaded and fluted barrel: 1/2×28 TPI thread pattern for suppressor or compensator compatibility; fluting reduces weight and improves cooling.
• Included night sights: Tritium front and rear sight set, pre-installed for zeroing, offering enhanced visibility in low-light environments.
• 15-round magazine: Factory-standard capacity, steel body with anti-tilt follower, compatible with P80 compact frames.

The p80 thr/flu brl n/sght 15rd is manufactured from 416R stainless steel with a black nitride finish for corrosion resistance and extended service life. The barrel is headspaced and tested for function with 9mm Luger ammunition. All components are new production and meet Polymer80’s quality control standards.

Who It’s For

This product is intended for the intermediate to advanced firearm builder who is assembling a Polymer80 frame from a completed 80% lower. It is also suitable for existing P80 pistol owners looking to upgrade their barrel, add a threaded muzzle option, or replace worn sights and magazines.

It is designed for legal, lawful use by individuals who are not prohibited from possessing firearms under federal or state law. This assembly is not intended for use with factory-manufactured, serialized frames from other brands without verification of compatibility.
