Frequently Asked Questions
Mossberg 590A1 50765 for sale
What's the difference between Mossberg 590 and 590A1?
The 590A1 features a heavier barrel, metal trigger guard, and metal safety button compared to the standard 590's polymer components. These upgrades improve durability under heavy use. The 590A1 also has a thicker barrel wall, making it mil-spec approved. Standard 590s are lighter and less expensive.
Can civilians buy a Mossberg 590A1?
Yes, civilians can buy the Mossberg 590A1. It's a pump-action shotgun widely available through licensed dealers, typically priced around $638. You'll need to pass a background check and comply with your state's firearms laws.
Can you shoot slugs out of a Mossberg 590A1?
Yes, you can shoot slugs from a Mossberg 590A1. Rifled slugs work reliably through the smoothbore barrel. Sabot slugs may tumble and lose accuracy without barrel rifling. Federal Truball slugs are a popular choice. Test different loads to find what your specific gun shoots most accurately.
Can you slam fire a 590A1?
No, the 590A1 has a disconnector that prevents slam firing. Older designs like the Ithaca Model 37 could slam fire, but the 590A1 requires the trigger to be released and pulled again between shots. Modifying it to slam fire would alter its design and may have legal implications.
Will the 590A1 shoot mini shells?
Not without an adapter. The stock 590A1 won't reliably cycle 1.75" mini shells due to receiver spacing. The OPSol Mini-Clip 2.0 fixes this but must be removed to shoot standard shells. The 590S model handles both interchangeably without any adapter.
Where is Mossberg 590A1 made?
Mossberg manufactures the 590A1 at its facility in North Haven, Connecticut, using primarily U.S.-sourced parts.
How does the 590A1 compare to the 500?
The 590A1 features a heavy-wall barrel, metal trigger housing, and metal safety button versus the 500's plastic components. Both are pump-action 12-gauge shotguns, but the 590A1's reinforced construction makes it more suitable for tactical and military use. The 590A1 typically costs around $638, more than the 500.
What is the Mossberg 590A1 special?
The Mossberg 590A1 is a pump-action 12-gauge shotgun built to military specifications, featuring a heavy-walled barrel, metal trigger guard, and metal safety. It meets MIL-SPEC 3443G standards and is designed for tactical and defensive use. It remains in current production with multiple variants available.
