Key Features
- Inertia-Operated Action — Why it matters: No gas system to foul or fail; runs dirty, runs dry, and cycles everything from low-recoil target loads to heavy magnum buckshot without tuning.
- Ported Vent-Rib Barrel (18.5″) — Why it matters: The porting reduces muzzle rise and felt recoil by up to 15%, keeping your second and third shots on target faster during rapid strings.
- Agency-Style Controls & Magazine Interface — Why it matters: Enlarged bolt release, extended safety, and flared loading port let you reload, clear malfunctions, and manipulate the gun under stress without fumbling.
- Picatinny Receiver & M-LOK Handguard — Why it matters: Mount optics, lights, lasers, or a foregrip directly without adapter plates; the M-LOK slots keep accessories low-profile and secure.
- Benelli/Mobil Choke System — Why it matters: Swap chokes in seconds to dial in your pattern for buckshot, slugs, or birdshot—versatility that matters when you don’t know what the day will demand.
Who It’s For
This shotgun is for the tech-forward shooter who wants a semi-auto that feels like a custom build out of the box. If you’re running drills, competing in 3-gun, or building a home-defense rig that you can actually maintain without a gunsmith, the MAC 2 Agency Tradesman is your next platform. Early adopters who appreciate Agency-style ergonomics and inertia reliability will find this hard to beat at this price point.
Pros & Cons
- Pro: Inertia system = zero gas fouling, less cleaning, more range time.
- Pro: Full-length Picatinny top rail accepts any red dot or reflex sight without adapter plates.
- Pro: M-LOK handguard is lightweight and lets you mount accessories exactly where you want them.
- Con: Fixed synthetic stock limits LOP adjustment; taller or shorter shooters may need to swap the stock for an adjustable option (aftermarket support is growing).
- Con: Inertia action can be finicky with extremely light target loads under 1,200 fps—stick to 1-oz loads or heavier for reliable cycling.

FAQ
What is the operating system of the MAC 2 Agency Tradesman?
It’s an inertia-operated semi-automatic system. There’s no gas piston or tube to clean—recoil energy cycles the action. This means less maintenance and more reliable function with a wide range of ammunition.
What choke system does it use?
The MAC 2 Agency Tradesman uses the Benelli/Mobil choke system. This gives you access to a huge aftermarket of chokes for buckshot, slugs, and birdshot—you can swap patterns in seconds.
Can I mount a red dot or light?
Yes. The receiver has a full-length Picatinny rail for optics, and the handguard has M-LOK slots on all four sides for lights, lasers, and foregrips. It’s ready out of the box for modern accessories.
Will it cycle light target loads?
Inertia shotguns generally prefer loads at or above 1,200 fps. For 1-oz target loads, it runs well. Extremely light 7/8-oz or 1,100-fps loads may not cycle reliably—use high-brass or heavier loads for guaranteed function.
What is the warranty on this shotgun?
Per MAC Armament, the MAC 2 Agency Tradesman comes with a limited lifetime warranty covering manufacturing defects. Always register your firearm on the manufacturer’s site to activate coverage.
