Frequently Asked Questions
Is this magazine permanently blocked to 10 rounds, or can it be restored to 30?
This magazine is sold as a California-compliant 10-round blocked magazine, meaning it has been modified to hold no more than 10 rounds. It is intended for use in states that restrict magazine capacity to 10 rounds. Attempting to remove or defeat the block to restore 30-round capacity would be illegal under California law and is not supported or recommended by Mission First Tactical or Goodland Guns.
Will this magazine work with .300 Blackout in addition to 5.56 NATO and .223 Rem?
Yes. The MFT EXD Window Magazine is designed to be compatible with 5.56 NATO, .223 Remington, and .300 Blackout cartridges, all of which share the same AR-15 magazine well dimensions. Always verify that your specific upper receiver and barrel are properly chambered for the round you intend to use.
How do I disassemble this magazine for cleaning?
The MFT EXD magazine features a tool-less takedown system with double floor plate safety release tabs. Simply depress both tabs simultaneously to safely release spring tension and slide the floor plate free. This design allows for quick field stripping, cleaning, and reassembly without any additional tools, making routine maintenance fast and straightforward.
