Description
Beretta took one of the most dependable gas guns on the market and set it up the way a defensive shotgun should be from the factory. The A300 Ultima Patrol runs a gas-operated action with a self-cleaning piston, which keeps recoil manageable and cycling consistent whether you feed it light training loads or full-power buckshot. The 19.1 inch chrome-lined barrel is chambered for 3 inch shells, and the extended magazine tube gives you 7+1 on tap, capped off with a barrel clamp that carries M-LOK slots and QD sling sockets.
What Sets This A300 Ultima Patrol Apart
This particular model, J32CTC11, ships with the billet aluminum Chisel stock instead of the standard polymer buttstock. It uses an AR-style grip, adjustable length of pull, adjustable cheek and recoil pad height, and a built-in RMR mounting plate positioned for a fast, natural sight picture. That means you can run a micro red dot without buying a separate mount, and dial the fit to your build and your gear. Up front you still get everything that made the Ultima Patrol popular: an enlarged loading port, extended bolt handle and bolt release, an oversized reversible safety, and aggressive texturing on the forend so your support hand stays planted.
Running the Ultima Patrol Day to Day
The ghost ring rear sight pairs with a post front for quick, repeatable aiming, and a 7-slot Picatinny rail sits on the receiver if you want an optic up top instead. The thin M-LOK forend takes a weapon light cleanly, and the whole gun is compatible with plenty of aftermarket 1301 Tactical rail and mount accessories. The barrel uses Beretta's Mobilchoke system with an Improved Cylinder tube installed, which patterns defensive buckshot nicely while leaving the door open for other constrictions down the road. At 7.1 pounds it carries easily, soaks up recoil better than most pump guns, and handles tight spaces without feeling like a club. If you want a semi-auto 12 gauge that is dialed in from the first shot, this one earns its spot by the bed or in the truck.

Frequently Asked Questions
Can I mount a red dot on the Beretta A300 Ultima Patrol Chisel?
Yes, and you have two options. The Chisel stock has an RMR mounting plate machined right in, positioned so the dot sits close to your eye for a wide field of view. If you prefer a receiver-mounted optic, the installed 7-slot Picatinny rail handles that too, and the gun is compatible with many aftermarket 1301 Tactical mounts.
Does the Chisel stock on this A300 Ultima Patrol fold?
No. The A300 platform houses its recoil spring in the stock, similar to an AR-15, so a folding stock is not an option on this gun. The Chisel stock is a fixed billet aluminum design, but it makes up for it with adjustable length of pull plus adjustable cheek and recoil pad height so you can fit it to just about any shooter.
Does this model come with removable choke tubes?
Yes, this version uses Beretta's Mobilchoke system and ships with an Improved Cylinder tube installed. That constriction patterns defensive buckshot well at typical home defense distances. Since the barrel is threaded, you can swap in other Mobilchoke tubes from Beretta or aftermarket makers like Carlson's if your needs change.
What ammo will the A300 Ultima Patrol cycle reliably?
The gas system with its compensating exhaust valve is built to run a wide range of 2 3/4 and 3 inch shells, from buckshot and slugs to most field loads. Owners consistently report smooth cycling with full-power defensive loads, and the gas operation noticeably softens recoil compared to a pump gun. As with any semi-auto shotgun, very light target loads are worth testing before you rely on them.
