The Ultimate Buying Guide for AR-10 .308 Magazines
Choosing the right magazine for your AR-10 rifle chambered in .308 Winchester is crucial. The magazine feeds the bullets into your rifle. A good magazine ensures smooth shooting. A bad one causes jams and frustration. This guide helps you pick the best one.
Key Features to Look For
When shopping, look closely at these main features:
- Capacity: Most standard AR-10 magazines hold 20 rounds. Some smaller ones hold 10 or 5 rounds, which are good for hunting or certain ranges. Bigger magazines (like 25 rounds) are heavier and might not fit all rifles well.
- Reliability (Feeding): This is the most important feature. The magazine must feed every round without fail. Look for designs that keep the cartridges stacked correctly.
- Lock-Up/Fit: The magazine needs to lock securely into the rifle’s magazine well. It should not wobble or fall out accidentally when shooting.
- Follower Design: The follower pushes the rounds up. A good follower is often made of durable polymer and has a smooth surface. It should move freely.
Important Materials and Construction
The material of the magazine heavily affects its lifespan and performance.
Metal Magazines (Steel or Aluminum)
Metal magazines are very strong. Steel is the most durable choice. It handles drops and rough use well. Aluminum is lighter but might dent more easily. Metal magazines sometimes need anti-corrosion coatings to prevent rust, especially if you shoot in wet weather.
Polymer Magazines
Modern polymer magazines are popular. They are lightweight and often cheaper. High-quality, reinforced polymers resist cracking. However, very cheap polymer can break if you step on it. Check reviews to ensure the polymer is tough.
Factors That Improve or Reduce Quality
Good design makes a big difference in how well the magazine works over time.
Quality Boosters:
- Anti-Tilt Followers: These followers prevent the top round from tilting sideways, which often causes feeding errors.
- Durable Springs: The spring pushes the rounds up. A high-quality spring maintains its strength longer. Weak springs cause failure to feed, especially with the last few rounds.
- Surface Finish: For metal mags, a good finish (like Cerakote or phosphate) protects the metal.
Quality Reducers:
- Thin Walls: If the magazine body is too thin, it can bend easily, causing the rounds to bind up.
- Poor Tolerances: If the magazine is made slightly too wide or narrow, it will not fit the rifle properly.
User Experience and Use Cases
Your intended use dictates the best magazine choice.
Range Shooting & Competition:
At the range, you want maximum capacity and fast reloads. 20-round magazines are standard. Look for easy-to-grip bases for quick changes. Reliability is non-negotiable here.
Hunting:
Hunters often prefer smaller capacity magazines (5 or 10 rounds). These keep the rifle slimmer and lighter for carrying through the woods. Durability against dirt and moisture is key.
Storage and Maintenance:
If you store the rifle loaded for long periods, some experts suggest storing magazines only partially loaded (e.g., 18 rounds in a 20-round mag). This helps the spring last longer. Always keep your magazines clean. Dirt inside the magazine is a common cause of malfunctions.
10 Frequently Asked Questions (FAQ) about AR-10 .308 Magazines
Q: Are AR-10 .308 magazines the same as 7.62x51mm NATO magazines?
A: Yes, generally they are interchangeable. The .308 Winchester and 7.62x51mm NATO cartridges are very similar, and most magazines work for both.
Q: Can I use standard AR-15 magazines in an AR-10?
A: No. AR-15 magazines are much smaller because they hold the 5.56 cartridge. They will not fit or function in the larger AR-10 platform.
Q: What is the standard capacity for an AR-10 magazine?
A: The standard capacity most commonly sold and used is 20 rounds.
Q: How do I clean my AR-10 magazine?
A: You should disassemble the magazine (carefully remove the spring and follower), wipe all parts clean with a dry cloth, and check for any debris. Do not use heavy oils inside the magazine.
Q: Why are some polymer magazines better than metal ones?
A: Polymer magazines are lighter and do not rust. Good ones offer excellent durability while reducing the overall weight of your rifle setup.
Q: What causes a magazine to “drop free” (fall out easily)?
A: If the magazine doesn’t lock in tightly, it might be due to the magazine catch slot being worn down, or the magazine itself being manufactured slightly out of spec. Good fit is essential.
Q: Should I buy brand-name magazines or generic ones?
A: For critical reliability, stick to proven, recognized brands. Generic, very cheap magazines often fail under stress.
Q: Do I need different magazines for different bullet weights (e.g., 150gr vs 180gr)?
A: Usually, no. A quality magazine is designed to handle the standard range of .308 bullet weights without issue.
Q: What is “over-insertion”?
A: Over-insertion happens when you push the magazine in too hard, causing the base plate to hit the bolt carrier group. This can jam the rifle. Some magazines have bumpers to prevent this.
Q: How long can I safely leave a magazine loaded?
A: While modern springs are strong, leaving them fully loaded for years can slightly weaken the spring. For long-term storage, loading to one or two rounds less than capacity is a safe habit.
