CAA Three Window Magazine
Command Arms Accessories (CAA) / EMA Tactical is proud to introduce our new and innovative Three Window Magazine. The Three built in windows allows the operator to see how many rounds remain in the mag.
This three window system allows the operator to keep track of his remaining rounds and facilitates timely magazine changes without the operator losing his sight picture. Simply glancing down at the back of the magazine from his cheek weld shows the approximate number of rounds remaining.
When the magazine is full the operator will see the brass round casings in the top and middle windows. The (orange) follower will appear in the bottom window indicating a full magazine of 30 rounds.
As rounds are fired, the operator glances at the middle window. When the middle window is empty only 19 rounds remain in the magazine.
Then the operator glances at the top window. When the top window is empty only 11 rounds remain.
This three window system shows that when the middle window is empty the operator has 2/3rds or fewer of the rounds remaining and when the top window is empty only 1/3 of the rounds remain in the magazine.

These look like a great idea. I like that the windows are on the back where you can see them while keeping your gun up on the treat area. Have they done any testing on how they hold up int he field?
