What are the key features of the Mossberg 590 Shockwave Flat Dark Earth Cerakote 12?
The Mossberg 590 Shockwave Flat Dark Earth Cerakote 12 brings a compact form factor to the reliable 590 platform. The 14-inch heavy-walled barrel is maneuverable, a characteristic often sought after for home defense applications. The Flat Dark Earth Cerakote finish isn’t just for looks; it provides a layer of protection against the elements, which is a practical consideration for any firearm. The Shockwave grip, unique to this series, allows for a shorter overall length while maintaining a non-NFA status as a ‘firearm,’ not a shotgun, due to its lack of a shoulder stock and specific length. It retains the familiar tang safety and dual extractors found on other 590 models, contributing to its robust operation. The drilled and tapped receiver allows for optic mounting, should you choose to enhance its sighting capabilities.

Frequently Asked Questions about the Mossberg 590 Shockwave
Is the Mossberg 590 Shockwave Flat Dark Earth Cerakote 12 considered a shotgun?
No, the Mossberg Shockwave is legally classified as a “firearm” under federal law, not a shotgun or a short-barreled shotgun. This is due to its overall length exceeding 26 inches and the fact that it was manufactured without a shoulder stock. It’s crucial to check your local and state laws, as some jurisdictions may have different interpretations or restrictions.
What kind of ammunition can I use with the Mossberg 590 Shockwave Flat Dark Earth Cerakote 12?
This model is chambered for 3-inch 12-gauge shells and can reliably cycle both 2-3/4 inch and 3-inch 12-gauge ammunition. It’s compatible with a wide range of loads, including birdshot, buckshot, and slugs.
How does the Flat Dark Earth Cerakote finish benefit the firearm?
The Flat Dark Earth Cerakote finish provides a durable, corrosion-resistant, and abrasion-resistant coating. It offers enhanced protection against rust, scratches, and general wear compared to traditional blued or parkerized finishes, extending the life and appearance of the firearm.
Is the Mossberg 590 Shockwave Flat Dark Earth Cerakote 12 suitable for home defense?
Yes, its compact size, maneuverability, and 12-gauge stopping power make it a viable option for home defense. The short barrel is advantageous in close quarters, and the pump action is known for its reliability.
Can I add a traditional stock to the Mossberg 590 Shockwave Flat Dark Earth Cerakote 12?
Adding a traditional shoulder stock to a Mossberg Shockwave with a barrel under 18 inches would legally reclassify it as a short-barreled shotgun (SBS), which is an NFA item. This requires federal registration and a tax stamp, and is subject to specific NFA regulations. Without proper registration, it would be illegal.
