The HERA Arms H2 Gen 2 AR-15 Magazine delivers German-engineered precision in a California-compliant, 10-round package — built with a full 20-round body for natural handling and reliable feeding in your 5.56 NATO or .223 Rem rifle.

  • Permanently blocked to 10 rounds via proprietary block and rivet for compliance
  • Full-size 20-round body retains familiar ergonomics and natural magazine changes
  • Compatible with AR-15 and M4-platform rifles chambered in 5.56 NATO and .223 Rem
  • Impact-modified polymer construction resists drops, impacts, and harsh field conditions
  • Stabilized feeder and mechanical stop prevent over-insertion on open-bolt lockback
  • Precision injection-molded in Lower Franconia, Germany on HERA's own tooling

Who This Is For

This magazine is an ideal choice for California-based AR-15 owners, competitive shooters operating under capacity restrictions, and anyone who wants a high-quality, compliant magazine that doesn't sacrifice ergonomics or reliability. It's equally well-suited for hunters, range shooters, and responsible gun owners in other states with 10-round magazine limits who refuse to compromise on build quality.

Frequently Asked Questions

Is the 10-round block permanent, and can it be removed?

Yes. HERA Arms uses a proprietary block-and-rivet system specifically designed to be permanent and tamper-resistant. This ensures the magazine meets the requirements of California and other states that mandate a maximum 10-round capacity. Attempting to remove the block would damage the magazine and is not recommended.

Will this magazine work with my AR-15 or M4-style rifle?

The HERA H2 Gen 2 is designed to be fully compatible with standard AR-15 and M4-platform rifles chambered in 5.56 NATO, .223 Remington, and .300 Blackout. It features a standard STANAG-style feed lip and body geometry, so it should drop in and lock up reliably in any mil-spec AR-15 lower receiver without modification.

Does the full 20-round body size cause any issues in California-compliant "featureless" or fixed-magazine builds?

No — the 20-round body is purely a form-factor choice that makes the magazine easier to handle and load, and it does not affect compliance. What matters for California law is the blocked 10-round capacity, not the external dimensions of the magazine body. Always verify your complete rifle configuration complies with current California firearms regulations.

    Sleek design, poor quality

    Posted by Brian Matyas on Mar 27th 2025

    I bought these mags for my DDM4V7 and unfortunately the build quality on these is pretty poor. The double stacking is sloppy, the plastic housing bubbles with 5+ rounds and it doesn't seat well at all in my AR. I have to forcibly smack it a few times to get it to seat.
