PSA 570 Shotgun: Modular 870-Compatible Pump Ships July 24

The PSA 570 is a 12-gauge pump-action shotgun designed around a single idea: let the owner reconfigure the gun at home instead of buying a new shotgun for every job. Palmetto State Armory built the receiver to accept Remington 870 aftermarket furniture and made the barrel and magazine tube quick-change with a custom wrench, so one 570 can move between a short home-defense setup and a longer general-purpose gun without a trip to a gunsmith. It is the pump shotgun answer to the parts-swapping culture PSA already feeds on the AR side.

The 570 name and the 870 compatibility are not subtle. This is a direct shot at the Remington 870, the pump that has defined the category for decades. The 570 keeps what makes the 870 ecosystem valuable, the enormous aftermarket of stocks and forends, and layers on modern features the 870 never shipped with: a factory optic cut, a Glock-style front sight, and a hanger system built for barrel swaps. For where the 870 sits against the rest of the field, see our best pump shotgun guide.

The receiver is the story. PSA milled it with a Trijicon RMR footprint, so an RMR-pattern red dot mounts directly to the top of the receiver with no adapter plate or rail riser. Out of the box the gun ships with a cover plate over that cut, and the cover plate carries a built-in backup rear sight that pairs with a Glock-style front sight. You run irons until you want a dot, then pull the cover plate and drop the optic on. For which dots make sense on a fighting shotgun, see our best red dot for shotgun guide.

The controls are laid out for hard use. A side-mounted action release sits where a right-handed shooter's trigger finger falls, and the receiver takes 870 furniture on both ends, so a buyer can bolt on a preferred stock and forend day one. The magazine tube and barrel lock up at the rear of the mag feed tube directly into the receiver, which is what makes the barrel and tube swaps possible without disturbing the optic zero on the receiver.

The free-float hanger is what earns the 570 the “build-it-yourself” label. On a traditional pump, the lockup is part of the hanger assembly, which ties the barrel, magazine tube, and receiver together as one fixed length. PSA moved the lockup to the rear of the magazine feed tube inside the receiver, so the hanger floats independently of both the barrel and the mag tube. That decoupling is the whole trick.

Because the hanger no longer sets the length, the owner can pull the barrel and magazine tube with a custom wrench and reinstall different lengths without machining or a gunsmith. PSA says it plans to sell barrels, magazine tubes, and standalone receivers separately after the initial launch, which turns the 570 into a platform rather than a single fixed model. Build a short, optic-equipped home-defense gun this weekend and a longer utility setup the next.

The PSA 570 launches in four configurations, split across two furniture packages and two colors. Two models wear PSA's own furniture, which adds built-in QD sling mounts on the stock and adjustable length-of-pull spacers so the gun fits shooters of different sizes. The other two ship with Magpul furniture, the same SGA-style stock and MOE-style forend that already have a following on the 870. Each package comes in black and Flat Dark Earth.

Every launch model shares the same core: an 18.5-inch barrel, 7+1 capacity, and a chamber that runs both 2.75-inch and 3-inch 12-gauge shells. That 18.5-inch barrel keeps the 570 a standard Title I shotgun with no extra paperwork, while staying short enough to work indoors. For the ammunition side of a defensive setup, our best buckshot and slug ammo guide covers the loads worth feeding it.

The PSA 570 is aimed squarely at the buyer who would otherwise pick up a Remington 870 and start swapping parts. It ships optic-ready and modular from the factory, which the base 870 does not, and the 870 furniture compatibility means the existing aftermarket is already there on day one. For a defensive shotgun, the 18.5-inch barrel, 7+1 capacity, and factory dot mount cover the fundamentals our best home defense shotgun guide calls for.

The open question is price, which PSA had not published as of the launch reveal. PSA's house-brand strategy has always been to undercut the incumbent, so the 570's value case rests on landing below a comparably equipped 870 while shipping the optic cut and modularity as standard.
