Each link opens the video at the moment quoted.* > Nice thing about the ghost ring sights on these guns is that you know you should be able to get a little bit of precision and they do pick up quite nice. > > — [Iraqveteran8888](https://www.youtube.com/watch?v=iu1GuKhC7bY&t=174s) > Much much better in terms of the group out of this gun that little rigid 14 inch barrel with the modified choke its grouping that buckshot really nice. > > — [Iraqveteran8888](https://www.youtube.com/watch?v=iu1GuKhC7bY&t=265s) > I think if this were going to be a truck gun or a home defense gun or something like that I think that's probably the round that I would stick with there. > > — [Iraqveteran8888](https://www.youtube.com/watch?v=iu1GuKhC7bY&t=273s) > You've got a lowly trigger guard you don't have to worry about those tabs breaking off like you would on a plastic trigger guard. > > — [Iraqveteran8888](https://www.youtube.com/watch?v=iu1GuKhC7bY&t=77s) ## What Customers Say *AI-generated insights from customer reviews* Owners of the Mossberg 590A1 consistently point to reliability as its core strength. Reports of cycling different ammunition types without issues are common, and the heavy barrel and parkerized finish are cited as evidence of durability-focused construction. Ergonomics draw positive comments. The grip and weight distribution are generally called comfortable. The 9-round capacity is a recurring positive for home defense buyers, and the tang safety location is praised for its accessibility. Weight is the most cited criticism; at 7.3 lbs some find it tiring during extended use or drills. Some owners note that recoil with heavy 12-gauge loads is substantial and recommend recoil pads or lighter shells. Factory sights get occasional requests for a ghost ring or rail upgrade rather than the basic bead. Value opinions vary. Most see it as worth the price given its track record, but a few feel comparable reliability is available at lower price points. ## Pricing **17 offers available** | Vendor | Price | |--------|-------| | Gunprime Com | $609.00 | | Grabagun Com | $649.99 | | Buds Gun Shop | $654.49 | | Gritrsports Com | $655.99 | | Shootingsurplus Com | $656.30 | | Kygunco Com | $673.89 | | Guns Com | $674.99 | | Centerfiresystems Com | $676.99 | | Gunbuyer Com | $686.89 | | Globalordnance Com | $688.36 | *...and 7 more offers* ## Reviews **Average Rating:** 5.0/5 (1 reviews) > **joey17** (5/5): Mine ran flawlessly through 125 shells from three different ammunition makers on its first skeet outing.
