Polymer80 P80 Thr/Flu Brl N/Sght 15rd

The Polymer80 P80 Thr/Flu Brl N/Sght 15rd represents a precision-engineered component for builders who demand exacting tolerances in their custom firearm projects. This barrel assembly, paired with a 15-round magazine compatibility configuration, is designed for users working within the P80 platform framework. Each unit is manufactured to strict specification standards, ensuring consistent performance across varying environmental conditions.

Overview

The p80 thr/flu brl n/sght 15rd designation refers to a specific Polymer80 barrel configuration that includes threaded muzzle features (thr), fluted external profile (flu), and a blank sight dovetail (n/sght) for aftermarket sight installation. This 15-round compatible assembly is machined from 416R stainless steel with a black nitride finish, offering corrosion resistance and reduced friction during cycling. The barrel is designed for direct fit into Polymer80 frames and slides without requiring additional fitting, though individual tolerance stacking may necessitate minor adjustment.

Features & Specs

• 416R stainless steel construction with black nitride surface treatment; 1:10 twist rate for stabilized projectile flight; fluted profile reduces overall weight by approximately 1.2 ounces while increasing surface area for heat dissipation
• Threaded muzzle (1/2×28 TPI) with protective thread cap; no front sight installed (n/sght) allowing custom height selection; 15-round magazine compatibility verified with standard P80 magazine catch geometry
• Bore diameter: 0.355 inches; rifling: 6-groove conventional; overall length: 4.6 inches; weight: 6.3 ounces; headspace gauged at factory to SAAMI minimum specifications

Gas port diameter is optimized for standard pressure 9mm loads, with a consistent chamber throat depth that supports both 115-grain and 124-grain projectile weights. Each barrel is individually inspected for concentricity and surface finish uniformity. The p80 thr/flu brl n/sght 15rd designation ensures compatibility with Polymer80 slide assemblies that utilize standard 9mm barrel lockup geometry.

Who It’s For

This barrel assembly targets intermediate to advanced firearm builders who have already completed a Polymer80 frame and slide assembly and are seeking a threaded option with a fluted profile for improved balance and heat management. The p80 thr/flu brl n/sght 15rd is specifically suited for users who intend to install suppressor-ready muzzle devices or aftermarket compensators while maintaining a 15-round magazine capacity configuration. Builders who prioritize weight reduction in the reciprocating mass without sacrificing barrel rigidity will find the fluted profile beneficial.

This component is not recommended for first-time builders unless they have access to appropriate headspace gauges and a dedicated barrel fitting fixture. The n/sght (no sight) configuration requires the user to install a front sight post, necessitating a dovetail sight pusher or press tool. The p80 thr/flu brl n/sght 15rd is also appropriate for gunsmiths building customer rifles where specific sight height adjustments are required.

• Requires Polymer80 or compatible slide with 9mm barrel channel; not compatible with subcompact frames without slide modification
• Threaded muzzle intended for permanently attached muzzle devices only in NFA configurations; verify local regulations before installation
• Not for use with +P+ ammunition; standard pressure 9mm rated up to 38,500 PSI

Shipping & FFL

This item is classified as a firearm barrel and does not require transfer through a Federal Firearms License (FFL) dealer for shipment. Polymer80 barrels are considered non-serialized firearm parts under current ATF regulations. However, some state and local jurisdictions may impose additional restrictions on threaded barrels or barrel assemblies. It is the purchaser’s sole responsibility to verify all applicable laws before ordering.

• Shipping via UPS Ground or FedEx Home Delivery; adult signature required at delivery
• No FFL transfer fee applies; ships directly to your verified shipping address
• Cannot ship to California, New York, New Jersey, Connecticut, Massachusetts, Maryland, Hawaii, or Washington D.C. due to threaded barrel restrictions

The p80 thr/flu brl n/sght 15rd is in stock and ready for immediate shipment. All orders are processed within 1 business day. Standard shipping timelines apply.
