When your mission profile demands more time on the sights and less time on the bench, capacity matters—but reliability matters more. I’ve run enough gear to know that the right magazine can make or break a rifle. Today, we’re looking at a high-capacity option built to feed clean, lock open when it should, and ride comfortably in standard pouches without the bulk of a drum.

Why this magazine stands out
High-capacity magazines aren’t new. What is new is getting 60 rounds on deck without the bulk and wobble of a drum. Built by Schmeisser and imported by American Tactical, this magazine uses a quad-stack internal layout to double up capacity while keeping an external profile that behaves like a classic AR mag. That means it slides into common AR-15 magazine pouches, locks into mag carriers, and seats in the rifle with familiar geometry—no weird angles, no awkward reloads.
Key features that earn a place on your belt
Quad-stack, 60-round capacity
The quad-stack design is the heart of the system. Internally, rounds stage in four columns, tapering to two as they rise, allowing you to carry up to 60 rounds of 5.56x45mm NATO or .223 Remington without the drum footprint. For patrol, competition, training days, or a long stint on the square range, that extra capacity reduces reload frequency and keeps your focus on fundamentals and problem-solving.
Fiberglass-reinforced polymer body
The body is heavy-duty fiberglass polymer—stiff enough to resist flex and heat, forgiving enough to handle impacts. In practical terms, you get rigidity for consistent feed geometry and durability when things get bumpy. The ribbed exterior provides a confident grip in rain, mud, or gloved conditions, which is exactly when you’ll appreciate traction the most.
Two-piece follower for smooth feeding
High-capacity mags live or die on their follower design. This one uses a unique two-piece follower that manages column transition and keeps rounds tracking straight up the feed path. That engineering detail is what prevents binding when the mag is fully loaded or when you’re shooting dynamic strings at speed.
Gen 2 upgrades: bolt hold open and ammo viewport
The Generation 2 model adds a more reliable bolt hold open engagement. That matters because an open bolt on empty is your immediate cue to reload, preserving rhythm and making your rifle honest about its status. The integrated viewport is a small but valuable addition—quick glance, quick count, no guessing. On a team range or during a long defensive course, tracking your remaining ammunition is a real edge.
Caliber compatibility: keep it 5.56/.223
This magazine is purpose-built for 5.56x45mm NATO and .223 Remington. If your rifle lives in those calibers, you’re in the sweet spot for reliable stacking and feed angle. Do not run .300 AAC Blackout in this magazine. The internal geometry and feed presentation are not designed for .300 BLK, and mixing the two can cause unsafe conditions. Keep your mags dedicated and clearly marked; your rifle (and your barrel) will thank you.
Real-world advantages on the clock
On the flat range, a 60-round loadout means fewer mag changes and more time diagnosing recoil, sight picture, and trigger work. In training blocks where you’re moving, communicating, and solving problems, eliminating a reload every 30 rounds reduces administrative handling and keeps you in the flow. For home readiness or ranch defense, it’s additional insurance without the unwieldy profile of a drum.
Carry and compatibility
One of the smartest aspects of this design is that the exterior remains close to a classic magazine profile. It seats in AR-15 magazine pouches and most Kydex carriers far better than drum options. If you’re already invested in a chest rig, belt-mounted carriers, or a plate carrier, you won’t need to overhaul your setup to run this mag. That matters for anyone who’s built their kit around consistent indexing and repeatable reloads.
Durability and handling under stress
The ribbed texture translates to a secure purchase in wet or cold conditions. Under time pressure, positive control during insertion and extraction is key. The reinforced polymer shell resists flexing that can cause feed lip spread and misfeeds in lesser designs. Between the sturdy body and the two-piece follower, this mag is set up to keep feeding when you load it to the gills.
Price and value
At $35.99, it’s priced to build a reliable rotation without raiding the ammo budget. For the cost of a few boxes of 5.56, you get a purpose-built magazine that stretches your training cycles, streamlines your reload cadence, and maximizes your time behind the rifle.
Tips for setup and use
Loading strategy
Seat rounds with a steady rhythm. With high-capacity mags, consistent pressure during loading helps the column settle correctly, especially for the first few cycles of use. After loading to 60, firmly tap the baseplate to encourage the stack to align.
Function check
Run a basic function test with your rifle: lock the bolt to the rear, insert the loaded mag with positive pressure, and run the bolt forward. Fire to lock back. Verify the Gen 2 bolt hold open engages reliably. Repeat with varying round counts—20, 40, full—to confirm consistency.
Mark your caliber
Because this mag is 5.56/.223 only, mark it clearly to avoid mixing with .300 BLK setups. Color bands, paint pens, or tape works. Keep your systems clean and separate.
Who benefits most
If you’re an AR-15 owner who values more time on the trigger without dragging a drum around, this magazine is built for you. It’s a smart add for patrol rifles, training rigs, predator control, and practical competition where reload reduction matters. The viewport and improved bolt hold open make it especially friendly for newer shooters developing round management skills, while the robust build meets the expectations of seasoned users.
Brand pedigree
Manufactured by Schmeisser and imported by American Tactical, this mag carries a reputation for smart German engineering paired with stateside support. The Gen 2 refinements—especially the bolt hold open engagement—reflect lessons learned from hard use and feedback from the field.
What to expect in the hand
In the rifle, the mag seats confidently. The ribbing bites into your palm during speed reloads, and the profile doesn’t snag like a drum against belts or buckles. On the move, it balances well and avoids the pendulum effect common to wider drums. It feels like a proper tool, not a novelty.
Bottom line from the range
The ATI S60 G2 MAGAZINE delivers what matters: 60 rounds of 5.56/.223 in a package that feeds smoothly, locks open reliably, and fits where your mags already live. The fiberglass-reinforced body, two-piece follower, improved Gen 2 bolt hold open, and ammo viewport combine into a magazine that’s ready for real work. At its price point, it’s an easy add to any AR-15 setup that values efficiency and dependable performance.
