Overview

The Nine Ball Non‑Recoiling Two‑Way Outer Barrel is a premium performance upgrade for the SIG Sauer ProForce M17 MHS gas blowback pistol, designed to deliver improved accuracy, consistency, and muzzle device compatibility. Unlike standard tilting outer barrels found on most GBB pistols, this fixed‑barrel design eliminates unwanted movement during the firing cycle, creating a far more stable shooting platform.

Precision CNC‑machined from lightweight aluminum, this outer barrel is built to perfectly match the dimensions of the M17 slide while offering the durability required for competitive and high‑round‑count use. Whether you’re chasing tighter groupings, consistent velocity, or the ability to run tracers and suppressors, this Nine Ball upgrade delivers across the board.

Fixed “Non‑Recoiling” Design Explained

Traditional gas blowback pistols rely on a tilting barrel system that moves during cycling. While functional, that movement can introduce minor inconsistencies in BB trajectory and velocity. The Nine Ball non‑recoiling system solves this by fixing the inner and outer barrels together using two precision grub screws.

By locking the barrel assembly in place, all barrel movement is eliminated during firing. This creates:

• A stable firing platform

• Consistent hop‑up alignment

• Improved shot‑to‑shot accuracy

• More consistent FPS readings

The result is a noticeably smoother and more predictable shooting experience, especially when paired with a tight bore inner barrel.

CNC Aluminum Construction

This outer barrel is manufactured from lightweight, durable CNC‑machined aluminum, striking the perfect balance between strength and weight. The reduced mass helps maintain smooth slide cycling while still providing excellent rigidity once fixed in place.

The black finish offers a clean, factory‑correct appearance that blends seamlessly with the ProForce M17 slide, making this upgrade as visually appealing as it is functional.

Two‑Way Threaded Versatility

One of the standout features of this Nine Ball outer barrel is its two‑way threading system, giving players maximum flexibility when running muzzle accessories:

• Native 11mm internal threads for direct attachment

• Included 14mm CCW adapter for compatibility with most airsoft suppressors, tracers, and compensators

When attachments aren’t needed, the included standard barrel crown can be installed to maintain a clean, streamlined profile.

This makes the barrel ideal for both CQB tracer builds and outdoor suppressed setups.

Precision Fit for the SIG Sauer M17

Designed specifically for the SIG Sauer ProForce M17 MHS, this outer barrel installs cleanly with no permanent modification required. The precision‑cut profile ensures proper slide clearance, reliable cycling, and consistent alignment with the hop‑up unit.

For best long‑term performance, thread‑lock adhesive is strongly recommended on the grub screws to maintain a secure fixed‑barrel setup under recoil.
