The look and quality is excellent. Beats waiting for a KAC to hit the market. My one issue is, once installed, the rails seem to not be parallel with the bore. this makes the rails seem to be canted upward the closer you get to the muzzle. Its not much but somewhat noticeable. also could make make zeroing a laser difficult
B&T Rail for MP5
The B&T rail is awesome! The engineering and the fit could not be better. The rail is super easy to install and comes with the tool needed to do so. It won't scratch your receiver like the Knight rail can, which is a huge plus in my book. Running mine on HK SP5 SBR.

Great rail for vertical grip and flashlight laser mount.
