Quoted: What do you think makes the military like the DD and KAC rails better than others? What do you like best about what you have compared to what you've seen. |
Those are rails that passed the military testing, and are in service with the military.
Asking what I like best may not be the question that is going to be of any help to you. My needs for what I do are quite different than what many other people do, so an honest answer from me may be of little to no use.
For my work as a city cop, I like Daniel Defense Lite rails. For overall rail choice, I like the RIS II series. These rails are not cheap, and the issue RIS II rail is just about impossible to get ( I know of 3 people outside the military who have them). For a drop in FF rail that requires no modifications, I think the DD Omega rail is a great choice. The downside would be the price, and that tools are required.
If we are talking about what rail gives the most bang for the buck when money is a tight, I would go with the MI rail series. The MI rail require removal of the delta ring (cutting it off), but thats a simple step, and there are guides that walk you through how to do that. I work with officers that use many different rail systems, and the MI have always held up very well.
