Top 16 Best Magazine For Diamondback 300 Blackout
Earlier many shooters had to use a magazine designed for another cartridge, using .300 Blackout in the AR-15 rifle, limiting its compatibility and performance. As a rule, 5.56x45mm becomes an alternative because of both cartridge parts’ compatibility.
Why do we need 300 Blackout Magazines?
It is better to choose a magazine specially chambered in .300 Blackout, because of increasing overall reliability, safer way to feed this round without dangerous cross-loading issues.

Lancer designed three magazine models: two 10-rd in Translucent Smoke and Opaque Black for .300 Blackout, and one 5-rd in Translucent Smoke for .223/5.56 calibers. There are particular molded .300 Blackout markings on the magazine body exterior.
