Description
Finding replacement magazines for vintage Remington autoloading rifles can be frustrating, but this 10-round magazine from Triple-K solves that problem. It's engineered specifically for the Remington 7400 and 742 models in 30-06 Springfield, giving you genuine extended capacity when factory originals are impossible to track down.
Built for Remington's Trusted Rifles
This magazine feeds .30-06 Springfield rounds through your 7400 or 742 action smoothly and consistently. The design also works in the Remington 740, 750, 760, and compatible models when chambered in 30-06, .270 Winchester, or .280 Remington. Triple-K manufactures these magazines with a 3-piece folded steel body reinforced by precision spot welds, creating a magazine that holds up to real-world use. The black finish offers corrosion resistance and a clean look that matches modern rifles or complements vintage guns.
Dependable Feed System
The magazine features a steel follower and a tested steel leaf spring that keeps rounds perfectly aligned in the magazine well. This is important because these rifles have earned a reputation for being finicky, but most feeding issues come down to dirty actions or worn-out magazines. A fresh Triple-K magazine with a solid spring typically runs without problems. Many owners report feeding smoothly after a light break-in, which usually just means cycling a few rounds through the magazine by hand before taking it to the field.
What to Expect
This is an aftermarket magazine, not an original Remington factory mag. It's a solid alternative when you need capacity and can't afford the premium price of vintage factory magazines. Some shooters find it requires light fitting or a cleaning cycle before it runs perfectly, especially in rifles with tight tolerances or that haven't been used in years. Once it's broken in, most users report reliable performance for hunting and range time.

Frequently Asked Questions
Will this Triple-K magazine work in both my 7400 and 742?
Yes. This magazine is designed for both the Remington 7400 and 742 semi-automatic rifles. It also fits the 740, 750, and 760 models when chambered in 30-06 Springfield, .270 Winchester, or .280 Remington. Just verify your rifle is in one of these calibers before using it.
Do I need to do anything before using this magazine for the first time?
Some users find it helps to cycle a few rounds through the magazine by hand before loading it into the rifle, especially if your rifle has been sitting unused. This helps break in the spring and ensure smooth feeding. Once it's been used a few times, it typically feeds reliably.
How does this Triple-K magazine compare to original Remington factory magazines?
This is a quality aftermarket replacement made with steel construction and precision welding. While it's not an original factory magazine, it gives you genuine 10-round capacity at a fraction of the cost of rare vintage originals. Many owners report flawless performance once broken in.
What makes this 10-round magazine different from the 4-round standard magazines?
This magazine holds 10 rounds instead of 4, cutting down on reloading time. The trade-off is that it won't hold the bolt open on the last round like 4-round magazines do, but it's great for hunting and range use when you want more trigger time between mag changes.
