Weighing in at just over five and a half pounds, this shotgun is easy to carry all day in the field. Its gas system is tuned for a wide range of loads—here’s the thing—you won’t need to adjust it between light target rounds and heavier hunting shells. The synthetic stock is durable and weather-resistant, ready for Missouri’s variable seasons. At $553.46, it represents a solid value in a reliable, purpose-built semi-auto. This firearm ships to Missouri and compliant US states, and an FFL transfer is required for firearm purchases.
Who It’s For
This is the shotgun you hand a new shooter when introducing them to wingshooting or clays. It’s for the young hunter needing a firearm that fits without awkward stretching. It’s also for the adult of smaller stature who’s tired of managing the length and weight of a full-size 12-gauge. When it comes to building confidence and skill, a gun that fits properly is non-negotiable. The 20-gauge chambering offers ample power for dove, quail, and squirrel, with manageable recoil that doesn’t instill a flinch.
Pros & Cons
Pros: The low-recoil operation is its biggest advantage, making extended practice sessions tolerable. The lighter weight and shorter stock directly address fit for its intended users. Reliability with a broad spectrum of ammunition means less fussing and more shooting. The 24″ barrel offers a good balance between maneuverability in brush and a smooth swing on crossing shots.
Cons: The youth stock may be too short for average or larger-framed adults without adding a spacer or replacement stock. As a dedicated field model, it lacks tactical features like extended magazine tubes or ghost ring sights—it’s a hunter, not a breacher. The 20-gauge, while versatile, has less payload options than 12-gauge for certain waterfowl or turkey scenarios.
Frequently Asked Questions
Q: Can an adult of average size use this shotgun effectively?
A: Yes, though the length of pull will be short. Many adults find it points quickly for fast, close shots. For a permanent fit, aftermarket stock spacers or a full-size Mossberg SA-20 stock can be installed—no gunsmithing required for a simple swap.
Q: What chokes does it come with?
A: It typically includes a set of interchangeable choke tubes (often Improved Cylinder, Modified, and Full), providing flexibility from open patterns for close-range skeet to tight patterns for turkey or passing geese.
Q: Is it reliable with light target loads?
A: The gas-operated system is specifically designed to cycle lower-power 2-3/4″ target loads reliably, which is a common point of failure in some inertia-driven systems. It’s built for the high-volume shooting of clay sports or dove fields.
