Beretta 1301 and A300 Owners Get a Shorter, Adjustable Stock
Reptilia has released the BPS, a drop-in stock for Beretta's 1301 Tactical and A300 Ultima Patrol shotguns. The name stands for Beretta Precision Stock. Without spacers, it gives you an 11.63-inch length of pull, which runs shorter than most stock setups on these guns. The package includes a 1-inch spacer for shooters who need more reach. Both shotguns are gas-operated autoloaders with very different internals, and the BPS fits both. For a defensive shotgun that sits in a closet for years, fit decides whether the first shot lands where you want it.
Key Details
The BPS is a polymer, aluminum, and steel build. Here is what the spec sheet shows:
- Length of pull: 11.63 in (29.5 cm) without spacers, 12.63 in (32.1 cm) with the included 1-inch Beretta spacer.
- Comb height: adjustable, so the cheek rest can match your sight picture.
- Weight: 14.5 oz (411 g).
- Body: impact-modified, glass-filled nylon polymer.
- Aluminum: 7075-T6 with a Type III hardcoat anodized finish.
- Hardware: nitrided alloy steel, with stainless steel screws in two lengths, 1.5 in (3.8 cm) and 2 in (5.1 cm).
- Compatible guns: Beretta 1301 Tactical and A300 Ultima Patrol.
The 1301 Tactical targets law enforcement and home defense. It runs Beretta's B-LINK gas system with a rotating bolt. The A300 Ultima Patrol carries the A300's gas system into a tactical setup. That system uses a self-cleaning cylinder and piston, a compensating exhaust valve, and a falling-block lock. Reptilia built one stock to cover both, which tells you the fit problem is the same across these platforms even though the actions differ. The comb adjustment matters most if you run ghost-ring sights from the factory or a red dot mounted on the receiver.
Background
Beretta's 1301 and A300 lines sit in the gas-operated autoloader category. Both rely on a gas system to cycle the action, and both have appeared in tactical configurations aimed at police and home defenders. Shotgun owners have long dealt with stock dimensions that do not suit every shooter. A stock that works for a tall shooter in a t-shirt often feels too long for a smaller shooter in a heavy coat. Aftermarket makers fill that gap by offering stocks with adjustable length, comb height, or both.
Length of pull matters more on a shotgun than on most rifles. Your cheek has to sit in the same place every time, and your eye has to line up with the sights or optic. If the stock is too long, you push the gun away from your face and lose your sight picture. If it is too short, you crowd the face and lose control. Reptilia's decision to start at 11.63 inches and add a spacer reflects that tradeoff. The spacer gives shooters a way to dial the length without buying a second stock.
Why It Matters for Gun Owners
If you own a 1301 Tactical or an A300 Ultima Patrol, this stock solves a fit problem before it becomes a range problem. Check your current length of pull. Mount the gun, close your eyes, and bring it up three times. If your head rides too far forward or back, your stock is wrong for you. The BPS gives you two starting points: 11.63 inches bare, or 12.63 inches with the spacer. That range covers many shooters who wear body armor or thick winter layers.
Winter carry changes the equation. A full-length stock can catch on a heavy jacket, and a bulky carrier can shift your cheek weld. A shorter stock keeps the gun tight to your shoulder and easier to manage while you move. Owners in cold-weather states, and anyone who runs a shotgun with armor on duty or in a home-defense drill, should pay attention to stock geometry. Before you buy, confirm that your model matches the BPS fitment. The release names the 1301 Tactical and the A300 Ultima Patrol, so check your exact variant against those names.
DownRange Analysis
A stock is not a constitutional question, so Bruen does not apply here. Bruen matters when the government decides who can own a shotgun or how you can use it. This is a product that helps you run a legal firearm better. It is a fit upgrade, and that is the right way to judge it. The spacer system is the smart part. A single stock that offers two lengths reduces the number of parts you need to buy and keeps the design simple.
The market implication is clear. Beretta owners have a limited set of aftermarket stock options, and every new drop-in replacement gives them a choice. Reptilia is betting that shooters want adjustability without a full custom build. Judge the BPS by range time, not by marketing. Measure your length of pull, set your comb height, and shoot a few hundred rounds before you trust the setup. If the fit works, keep it. If it does not, return to the spacer and check your numbers again.
