This is a pretty good rail, however it is not an accurate replica. This rail lacks the Keymod on the bottom making it incompatible with any low profile hand stops or Noveske rail segments. The noveske rails have sections that are milled out to further lighten the rail. Madbull rail segments are just solid pieces of metal and add a lot of weight if they are attached to the front of the gun.
This is a huge bummer for me because I wanted to use a low profile Noveske hand stop, but now I have to use a bulk rail segment and AFG to accomplish my goals. I really wish madbull had spent the time to make an ACCURATE replica, not just half of a good job.
Other than that, the rail feels light and solid. I'm just disappointed Madbull failed to replicate the real rail.
Lightest rail avaiable
Cheap price (compared to RS)
Not a very good replica. Sort of like madbull's take on the NSR system, not the real system.
