Overview
Built for 9mm AR-pattern builds, this straight-profile barrel is intended for shooters assembling an EPC upper or a compatible mil-spec upper receiver. Its 1/2-28 threading provides flexibility when selecting a muzzle device, while the integrated barrel extension keeps the stated length representative of the barrel itself. The design supports both Colt/RR and Glock style configurations, making it a practical choice for a range of 9mm carbine setups. Available in multiple lengths, it gives builders options without adding unnecessary complexity to a blowback system that does not require a gas block or gas tube.

Considerations & Trade-offs
- Designed for 9mm AR builds, so it is not a general-purpose barrel for other chamberings or platforms.
- The 1/2-28 threading offers muzzle-device flexibility, but it also means you’ll need to confirm thread compatibility with your chosen accessory.
- Compatibility is listed for both Colt/RR and Glock style AR builds, but the rest of the setup still needs to match your receiver and blowback configuration.
- The stated barrel length includes the integrated barrel extension, so the usable barrel length is not the same as the full listed measurement.
Suggested Comparisons
