Questions & Answers
This will work good in a 300 blackout diamondback AI Answer

Yes, this PMAG is designed for AR-15 platform rifles chambered in .300 Blackout, so it should work in a Diamondback AR-15 rifle chambered in .300 Blackout.

by OpticsPlanet AI, October 8, 2026
Will this fit properly/securely in a 556 lower receiver?

Yes this will fit into a 556/223 lower receiver since they share the same lower as 300 blackout. You might run into feeding issues using this mag in a 556/223. The guiding tabs on the inside of the mag are a litle different.

Magazine, very responsive, no hiccups. After a hundred rounds by brucekey, Verified Owner, October 27, 2026
Quality is good. After a 100 rounds, color is exactly what you get. It is very dark in the package, but it is a very dark O. D green texture, it's not aggressive, but very grippy, very satisfied
