Bastard Tri-Lug
Large-bore tri-lug muzzle device compatible with standard 9mm tri-lug adapters.
The Bastard Tri-Lug is designed for shooters running .45 ACP, 10mm, and other large-bore PCC or SMG platforms who want to use the far more common and standardized 9mm tri-lug ecosystem.
Unlike many dedicated .45 tri-lug systems, which often suffer from inconsistent dimensions and poor cross-brand compatibility, the Bastard Tri-Lug allows you to use standard 9mm tri-lug adapters while safely passing projectiles up to .458 caliber.
This allows a single suppressor setup to move seamlessly between:
- 9mm firearms using standard tri-lug muzzle devices
- .45 ACP and 10mm platforms using the Bastard Tri-Lug
No more thread adapters. No proprietary mounting system. No compatibility guessing. No more headaches!
Technical Overview
The Bastard Tri-Lug is a muzzle device that accepts standard 9mm tri-lug adapters while being bored for projectiles up to .458 caliber. It is threaded for direct installation on larger caliber PCC and SMG platforms without requiring additional adapters.
This solves several common issues associated with large-bore tri-lug systems. Many .45 caliber tri-lug muzzle devices and adapters on the market lack consistent dimensional standards between manufacturers, and compatible mounts and adapters are often limited in availability.
With the Bastard Tri-Lug, shooters running a .45 ACP or 10mm suppressor can simply install a standard 9mm tri-lug adapter onto the suppressor and use it across both 9mm and larger caliber firearms.
Use standard 9mm tri-lug muzzle devices on your 9mm platforms, and the Bastard Tri-Lug on your large-bore platforms — all while maintaining compatibility with the same suppressor mounting system.
Why Use a 9mm Tri-Lug System?
The 9mm tri-lug market offers:

The Bastard Tri-Lug brings those advantages to larger caliber platforms.
