Key Features
- Adjustable Synthetic Stock — WHY IT MATTERS: Lets you dial in length of pull and comb height for a perfect fit, improving mount consistency and reducing felt recoil.
- 26″ Vent-Rib Barrel with HiViz Fiber Optic Front Sight — WHY IT MATTERS: The vent rib reduces heat mirage, while the bright fiber optic front gives a clear sight picture for fast target acquisition on clays or birds.
- Nickel-Boron-Coated Internals — WHY IT MATTERS: This coating cuts friction and resists corrosion, keeping the action slick and reliable even in wet or dusty conditions without heavy lubrication.
- Briley Extended Chokes (Set Included) — WHY IT MATTERS: Briley chokes are a trusted name in precision patterning; the extended design makes swapping chokes quick without a tool, giving you choke options for everything from skeet to sporting clays.
- Corrosion-Resistant Gas System — WHY IT MATTERS: Reduces maintenance frequency and extends the life of the shotgun, especially when running high-volume rounds in competition or practice.
Who It’s For
This shotgun is for the competitive clay shooter who wants a reliable, adjustable semi-auto without the premium price of European brands. It’s also a strong pick for hunters who shoot high-volume waterfowl loads and want reduced cleaning time. The adjustable stock makes it a solid option for shooters with shorter or longer arms who need a custom fit.
Pros and Cons
- Pros: Smooth cycling with light loads; easy to clean; adjustable stock fits most shooters; Briley chokes add value; durable finish holds up to heavy use.
- Cons: The synthetic stock feels less premium than wood options; some shooters may prefer a longer 28″ barrel for trap; no mid-bead sight included.

FAQ
Does the Mossberg 940 Pro Sporting cycle light target loads reliably?

It includes a set of Briley extended chokes: typically Improved Cylinder, Modified, and Full. These are stainless steel and designed for quick, tool-less changes.
Can I adjust the stock for a custom fit?
