Frequently Asked Questions

Why does this magazine have a 20-round body but only hold 10 rounds?

This magazine is permanently blocked to a 10-round capacity to comply with California's magazine capacity restrictions. The blocking is built into the internal follower and body, so the magazine retains the ergonomic profile and handling feel of a standard 20-round mag while remaining fully legal for California residents to purchase and possess.

Will this magazine work with my 300 Blackout AR-15 upper, including suppressed configurations?

Yes. This D&H Tactical magazine is specifically designed for AR-15 platforms chambered in 300 Blackout. The feed geometry is optimized for 300 BLK cartridges in both supersonic and subsonic configurations, making it compatible with suppressed setups as well as standard unsuppressed builds. Always verify compatibility with your specific lower receiver before use.

Can I use this magazine in a standard 5.56/.223 AR-15?

No. While this magazine shares the same external AR-15 form factor, it is specifically configured for 300 Blackout ammunition. Using it in a 5.56/.223 chambered rifle is not recommended, as the feed lip geometry and follower are tuned for the 300 BLK cartridge's different bullet profile and overall length. Always match your magazine to your rifle's caliber for safe and reliable operation.
