Frequently Asked Questions

Will this magazine work with any 300 Blackout AR-15 upper?

Yes. The AMEND2 Mod-3 is designed specifically for 300 Blackout chamberings and fits any standard AR-15 lower receiver with a mil-spec magazine well. It will not reliably feed 5.56 NATO or .223 Remington ammunition, so ensure your upper is correctly chambered in 300 BLK before use.

Is this magazine truly California compliant?

Yes. This magazine is blocked to a 10-round capacity to comply with California's magazine capacity restrictions, making it legal to purchase and use in the state. The magazine features a full 30-round body profile, giving you a familiar ergonomic grip and handling feel while remaining within the law.

How durable is the AMEND2 Mod-3 polymer construction compared to metal magazines?

The Mod-3's impact-resistant polymer is engineered to perform across a wide temperature range — from freezing cold to extreme heat — without cracking, warping, or binding. AMEND2 subjects these magazines to rigorous testing including high round-count and drop tests. The self-lubricating follower also reduces wear over time, making it a long-lasting alternative to traditional aluminum magazines.
