Frequently Asked Questions
Is the 10-round block truly permanent and California-compliant?
Yes. DURAMAG uses a proprietary internal block secured with a steel rivet to permanently limit capacity to 10 rounds. This method is designed to meet the requirements of California and other states that restrict magazine capacity, and the block cannot be removed without destroying the magazine. Always verify current local regulations before purchasing.
Will this magazine work with my .300 Blackout AR-15?
Yes — DURAMAG's 10-round aluminum magazine is compatible with .300 Blackout in addition to 5.56 NATO and .223 Rem, as all three calibers share the same AR-15 magazine dimensions. The advanced internal geometry and anti-tilt follower help ensure reliable feeding across all three compatible calibers.
Can I leave this magazine loaded for long-term storage without damaging the spring?
Absolutely. One of the key advantages of DURAMAG's aluminum construction and premium spring design is that the magazine can be stored fully loaded for extended periods without the spring fatigue or body deformation that can affect polymer magazines. No additional follower upgrades or modifications are required for reliable long-term storage.
