There are several rounds that have been adopted to produce a more capable AR pattern rifle. Some are designed to give the AR-15 better range than the typical 5.56mm chambering. Other cartridges focus on delivering enhanced power.
6.8 SPC is one of those rounds. It’s designed as a direct upgrade over the 5.56mm round, which is cool.
Unfortunately, unlike other AR-15 rounds like the 300 Blackout, 6.8 SPC requires different magazines than 5.56mm. I imagine that’s why you’re here to learn about the best 6.8 SPC magazines.
Well, we’ve got them.
SPOILER—the Barrett Firearms MFG Inc. Barrett AR-15 30RD Magazine 6.8 SPC are the best 6.8 SPC magazines. They’re steel. They hold 30 rounds. And they’re reliable.

1. Barrett Firearms MFG Inc. Barrett AR-15 30RD Magazine 6.8 SPC - Overall Best 6.8 SPC Magazines
The Barrett Firearms MFG Inc. Barrett AR-15 30RD Magazine 6.8 SPC easily wins the overall best 6.8 SPC magazines spot because it’s one of the only 6.8 SPC 30-round magazines. And it’s one of the only 6.8 SPC 30-round magazines that runs reliably.
First, this is a steel magazine. And the steel is coated in a teflon finish. The coated steel feeder pawls put up very little friction. This reduced friction produces a very smooth action and reliable feeding.
There’s also an anti-tilt follower at the bottom of this magazine. The coated steel feed lips coupled with the anti-tilt follower are why this magazine operates so reliably. Everything works to eliminate hangups.
The only trouble with the steel construction is that it can warp over time or get bent if you abuse it too much during training. Polymer is less prone to issues caused by this sort of warping or damage.
So keep an eye on your magazines to ensure that they’re within spec.
Oh, one more thing: these magazines are a bit pricey. Barrett has never been one to produce budget equipment. But the quality is on par with the price.
If you want reliable 6.8 SPC magazines, Barrett 6.8 SPC magazines are your best bet.
2. Ammunition Storage Components AR-15 6.8 SPC Stainless Steel Magazine - Budget 6.8 SPC Magazines
Ammunition Storage Components has a pretty strong reputation for building affordable and reliable magazines. They’ve produced a few duds.
But the Ammunition Storage Components AR-15 6.8 SPC Stainless Steel Magazine is no dud.
This magazine is stainless steel, which is nothing new.
However, the finish is a proprietary coating that actually gets smoother as the magazine breaks in. The coating is also super corrosion resistant. So your magazine will last for a really long time. And these magazines will just get better the more you use them.
Additionally, these magazines are stuffed with a self-lubricating anti-tilt follower. This eliminates hangups inside the magazine which magazines for specialty rounds are often known for.
One more thing: these magazines are available in 5, 10, and 30 round capacities. That’s great, since you can get magazines that work for whatever type of shooting you do.
There’s just one downside: the 30 round model is only available in flat dark earth.
Obviously, that’s not a huge deal. It’s just a color. But I prefer plain black magazines. And usually colored magazines cost a tad more than standard black magazines.
But, even if you have to settle for FDE magazines, these ASC magazines operate smoothly. And they’re super affordable. If you’re trying to get the most 6.8 SPC magazines without busting your budget, these magazines are your best bet.
3. Duramag 6.8 SPC Stainless Steel AR Magazine - Value 6.8 SPC Magazines
Duramag is another brand that produces very affordable magazines, but produces the occasional lame duck. However, the Duramag 6.8 SPC Stainless Steel AR Magazine is durable and remarkably reliable.
There are 3 things that separate these magazines from similar 6.8 SPC magazines:
First, the body shape. The inner dimensions are slightly different than a standard 6.8 SPC magazine. The shape provides more space for rounds to move smoothly, even if there’s debris inside the magazine.
Then, the proprietary coating produces the lowest possible friction both inside the magazine and at the feed lips.
Last thing: the anti-tilt follower. These magazines use the Snap-On anti-tilt follower. The main benefit of the snap-on followers is that they can be trimmed to fit the magazine.
Ultimately, all these features add up to give you the smoothest, most reliable feeding possible.
The only downside is that these are still steel magazines which are not immune to things like warped feed lips. Eventually you may get some failures.
Also, these magazines are only available in 5 and 10 round capacities. A 30-round model would be a nice addition to the lineup.
But, if you have a designated marksman rifle or just prefer less bulk and weight, these Duramag magazines are a super affordable and reliable solution.
4. Precision Reflex Inc. AR-15 Magazine 6.8 SPC - Durable 6.8 SPC Magazines
The Precision Reflex Inc. AR-15 Magazine 6.8 SPC is a steel magazine that’s designed to be more durable and longer lasting than traditional steel magazines.
How does that work?
Simple: these magazines are stamped with a waffle pattern on the side of the magazine body.
The waffle pattern helps reduce flex and warping. That way your magazines stand up to abuse better. And you get a lot more shooting before the feeder pawls warp enough to cause feed issues.
These magazines double down on the body reinforcement with additional tempering on the feed lips to give your magazines the absolute longest lifespan possible.
But the waffle pattern has other benefits: these magazines are much easier to grip and manipulate than standard steel magazines. Not that traditional steel magazines are really that hard to handle. But more grip is better.
Additionally, these magazines are less prone to bending if you drop them. So they’re excellent training magazines.
Also, these magazines are filled with Magpul anti-tilt followers, which are pretty much considered to be the gold standard when it comes to AR-15 magazine followers.
These Precision Reflex magazines focus on durability. So the coating isn’t as smooth as some other magazine options. But the coating is corrosion resistant. And there are no feed issues with these magazines.
The price is a tad high. However, you’ll probably still get the most shots-per-dollar from these magazines, because the construction is so tough. So they’re a good investment, despite the higher price.
5. Wilson Combat AR Style Magazine - One-Piece 6.8 SPC Magazines
Most steel magazines are constructed by spot welding two pieces of steel together. This presents some obvious potential points of failure. The Wilson Combat AR Style Magazine takes a different approach, to avoid this problem altogether, without using polymer construction.
The body is a single piece of steel that is bent and stamped into shape. This construction has half the potential points of failure as the 2-piece construction. This magazine is much more resistant to warping and bending, and therefore lasts much longer.
Additionally, the body is stamped with a waffle pattern to reinforce the body and make this magazine even more durable.
The waffle pattern also gives you better grip and control over your magazine during loading and reloading.
Lastly, this magazine is fitted with a Magpul anti-tilt follower to ensure that your rounds stay aligned and feed properly every time.
Unfortunately, this Wilson Combat magazine is fairly expensive, especially for a 10-round magazine.
However, it will last longer than almost any other steel magazine. So the investment is worthwhile.
6. Daniel Defense PRI 5 Round Rifle Magazine - Precision 6.8 SPC Magazines
The Daniel Defense PRI 5 Round Rifle Magazine is designed for precision rifles that need reliability and durability more than magazine capacity. That’s why this magazine only comes in a 5-round capacity.
Now, this is a steel magazine. Standard stuff. There’s nothing super special about the construction.
But there are a couple perks:
First, the body is stamped with a waffle pattern. And it’s also stamped opposite the way that most waffle patterns are stamped.
The ridges of the waffle pattern are raised on this magazine. This makes the magazine body more durable. However, it gives you even better grip for loading and reloading than a waffle pattern with the ridges indented.
On the bottom, this magazine has a push-button floor plate. This makes it easy and fast to disassemble your magazine. So you have no reason not to keep your magazines clean and well-maintained.
This model is also fitted with a Magpul anti-tilt follower. This gives you the most reliable feeding.
And the coating on this magazine is super smooth. That gives you a super smooth action, as well.
Now, these magazines are expensive. However, they’re super durable, reliable, and they’re easy to maintain.
With a little work, you can keep these Daniel Defense magazines running smoothly for much longer than any other magazine, which makes these a great investment, even with the higher price.
