I'm looking to replace the 12" quad rail on my rifle with something slimmer/lighter/smoother. Guessing either Keymod or M-lok. Is there an advantage to one or the other? Anybody got any recommendations for a specific one, under $100? I don't know a whole lot about them, but my understanding is that the barrel nut is the difference between "cheap" ones and "good" ones....

The quad rail is just overkill. The only attachments I have are a flip up iron sight and a light, so I figured I could just put individual rail pieces where I need them instead of having 4 full-length rails. Hopefully making it a hair lighter and more comfortable to shoot.


There are 3 certainties in an uncertain world:

1. All Politicians Are Liars
2. All Gun Laws Are an Infringement
3. Taxation Is Theft
