I thought it looked familiar!
I had heard of ACOG sights, holographic, red-dot, etc., and I’ve played with a few at gun shows.
But, the hybrid was completely new to me. I had to look-up whether it really existed, or whether it was something they had invented for the game (though COD is usually pretty good about using real tech — at least before the next game, which is intentionally futuristic).
