If you run a 5.45×39 AK, the Arsenal Circle 10 M-74B45 sits in that sweet spot between practicality and firepower. It's 45 rounds of capacity without the complexity or bulk of a drum magazine, making it genuinely useful at the range or for competition without becoming a logistical headache.
Arsenal started with the same high-quality material and manufacturing process as their proven M-47W, then engineered it specifically for 5.45×39. The waffle-pattern polymer body isn't just aesthetic—it's functional. That pattern adds rigidity and longevity to the magazine, and it gives you a better grip when you're swapping mags fast. Inside, you get the hardware that separates Bulgarian magazines from everything else: steel feed lips that stay sharp through thousands of rounds, steel reinforcements front and back, and a steel locking lug that locks into your receiver with zero wobble.
These magazines have a track record that speaks for itself. They pass 100 percent of military drop tests 100 percent of the time, which means if you bump your loaded rifle or drop it on concrete, the magazine stays intact and functional. The machined wear-resistant lugs guarantee a perfect fit every time you load up, and the removable steel floorplate makes cleaning and maintenance straightforward when you need it. With a controlled-tilt polymer follower and a music wire spring, feeding is consistent and reliable, whether you're running a standard build or something more specialized.
You get a single magazine built to mil-spec dimensions that interfaces seamlessly with AK-pattern rifles in 5.45x39mm. It's a factory original from Arsenal Bulgaria—the same company that's been making AK components since 1878.
No. This magazine is specifically designed for AK-pattern rifles chambered in 5.45x39mm only. The AK-47 uses 7.62x39mm, which has entirely different magazine dimensions. Always verify your rifle's actual caliber before ordering—the two are not interchangeable.
The waffle pattern adds structural rigidity to the polymer body and extends the magazine's service life under tough use. It also gives you better grip when handling and indexing magazines during reloads, which matters more at speed than you'd think.
Yes. The M-74B45 has a removable steel floorplate, so you can break it down quickly for maintenance. This is useful after a dirty range day or if you need to inspect the internals for any reason.
You get 15 extra rounds in roughly the same ergonomic profile, which is a solid gain without the mechanical complexity of a drum. It adds length and weight, but experienced users find the trade-off worth it for extended range sessions or competition. If you're new to 5.45, start with standard 30-round mags and add these when you know what works for you.
