Frequently Asked Questions
Is the 10-round capacity block truly permanent?
Yes. DURAMAG uses a proprietary internal block secured with a rivet to permanently limit this magazine to 10 rounds. The block is not designed to be removed, and attempting to do so would damage the magazine. This method meets the permanence standards required for compliance in California and other restricted states.
Will this magazine work with my .300 Blackout AR-15 build?
Yes — this DURAMAG is compatible with rifles chambered in .300 BLK in addition to 5.56 NATO and .223 Rem, provided your rifle uses a standard AR-15/M4 lower receiver. The geometry and feed lips are designed to reliably feed all three of these cartridges without modification.
Can I leave this magazine loaded for long periods without damaging it?
Absolutely. One of aluminum's key advantages over polymer is its dimensional stability under sustained spring pressure. DURAMAG's aluminum body will not flex, swell, or warp when kept loaded for extended periods, making it an excellent choice for home defense or range storage use. The hard-anodized finish also protects against corrosion over time.

The best AR mags
Duramags by C Products are the gold standard for GI style mags. For state restricted mags, these look great compared to the neutered 10 rounds mags. More to grip onto and easier to insert / remove from mag well than pmags. Highly recommended. Great price.
