This is the Lancer L7AWM GEN 2 AR-10 .308/7.62×51 10-round magazine. 

Why settle for polymer or steel when you can have a hybrid magazine that incorporates both?!

Lancer magazines combine a lightweight polymer body with hardened steel feed lips to deliver superior durability. Inside, you’ll find an anti-tilt polymer follower and stainless steel spring, which keep every round perfectly aligned and ready to go. 

A switchable drain lock in the floor plate can be used if shooting in wet conditions, proving that Lancer has thought of nearly everything! Whether you’re hunting, training, or preparing for the zombie apocalypse, these Lancer L7AWMs are up to the task!
