Description
The Magpul Industries M3 is an AR-pattern magazine, 30 rounds, .300 AAC Blackout.
It feeds .300 AAC Blackout. Magazine and chambering have to match – cartridges differ in length and case shape, and a magazine built for one will not feed another reliably even where it physically fits.
Magazine capacity is restricted in some states and cities, and the limit is on possession, not just sale. Check your local rules before ordering – if you are unsure, ask us first.
This is a part or accessory, not a firearm, and ships directly to your address.
