Remington 783 Magazine Capacity Options Explained
The Remington 783 ships with a 4-round magazine, but that's not your only option. Depending on your caliber and how you shoot, you can run the standard flush 4-rounder, step up to an 8-round extended magazine, or — if you shoot .450 Bushmaster — a dedicated 3-round magazine. Here's how the capacities break down and which one fits your rifle.
Quick answer
Standard Remington 783 magazines hold 4 rounds. Our 783 XT holds 8 rounds in the short action. The .450 Bushmaster magazine holds 3 rounds because of its larger case. All are steel, US-made, factory-pattern replacements.

- Frequently asked questions
The standard 4-round magazine
Four rounds is the factory count for the Remington 783 across its standard calibers. The standard magazine sits nearly flush with the stock, keeping the rifle's low, snag-free profile — which is exactly what most hunters want. We build it in both short-action and long-action lengths so it matches your caliber. It's the right choice if you value a compact, factory-original feel.
The 8-round 783 XT
Want to double your on-board capacity? The 783 XT holds 8 rounds in the short action. It's purpose-built for the Remington 783 short-action rifles, so you get the extra capacity without giving up feed reliability. The trade-off is a magazine that extends below the stock rather than sitting flush — a fair exchange when you want fewer reloads at the range or on a longer sit in the field.
The 3-round .450 Bushmaster magazine
If your 783 is chambered in .450 Bushmaster, capacity works differently. The .450 is a large straight-wall cartridge — physically much bigger than a .308 or .270 — so its dedicated magazine holds 3 rounds. That's the correct, reliable count for a case that size, and it's a straight-wall-legal option for hunters in states that require it.
Which capacity is right for you?
| Magazine | Capacity | Best for |
|---|---|---|
| Standard (SA or LA) | 4 rounds | Hunting; flush, factory-original profile |
| 783 XT (short action) | 8 rounds | Range days, longer sits, fewer reloads |
| .450 Bushmaster | 3 rounds | Straight-wall cartridge rifles |
Key takeaways
- Standard 783 magazines hold 4 rounds; the 783 XT holds 8.
- The .450 Bushmaster magazine holds 3 because of its larger case.
- Match capacity to how you shoot — flush for hunting, extended for the range.
- Always match the magazine to your action length and caliber first.
Frequently asked questions
How many rounds does a Remington 783 magazine hold?
The standard factory magazine holds 4 rounds. Our 783 XT extended magazine holds 8 rounds in the short action, and the .450 Bushmaster magazine holds 3.
Is there a high-capacity magazine for the Remington 783?
Yes. The 783 XT is an 8-round extended magazine for the short-action 783 — double the standard capacity.
Why does the .450 Bushmaster magazine only hold 3 rounds?
The .450 Bushmaster is a large straight-wall cartridge with a much bigger case than a standard 783 round, so 3 rounds is the correct capacity for reliable feeding.
Does the 8-round XT fit a long-action 783?
The 783 XT is built for the short action. If you have a long-action 783, use the long-action magazine; contact us about capacity options for your caliber.
