Frequently Asked Questions
Is the 10-round block truly permanent, and can it be removed?
Yes. DURAMAG uses a proprietary block-and-rivet system specifically engineered for permanence. The block is not a simple insert — it is mechanically riveted inside the magazine body, making removal extremely difficult and ensuring the magazine remains compliant with capacity restrictions. This design meets the legal requirements for permanently altered magazines in California and similar states.
Will this magazine fit all standard AR-15 lowers, and does it work with .300 Blackout uppers?
Yes — this DURAMAG is designed to the standard AR-15/M4 STANAG specification, so it seats and locks in virtually all mil-spec and commercial AR-15 lower receivers. It is also fully compatible with .300 Blackout uppers, giving shooters added versatility across different upper configurations on the same lower platform.
Can I store this magazine loaded for extended periods without damaging the spring?
Absolutely. One of the key advantages of DURAMAG's aluminum construction is that the magazine body will not flex or take a set under sustained spring pressure the way polymer magazines can. The high-quality spring is rated for extended loaded storage without loss of tension or feeding reliability, so you can keep it staged and ready without worry.

Perfect for dry fire
The blue is commonly used for simunitions but I found it perfect for dry fire/dummy rounds.
