I got this M4S on my AR.
I was deciding to get T-1 or M4s. and got M4s with
LaRue mount. It is durable and clear in optical view.
I really like it. But if you want light, compact RDS,
go with T-1 or H-1. M4s also shines with AA battery choice since it is easy to get. overall, it is excellent choice for CQB.
Pros: Durability, awesome battery life. clear optical performance
Cons: Big, heavy
