Quad rails differ from company to company, but they all have the same basic design. And where the military and LEOs go, the civilians follow, because the military and LEO guys know best. The quad rail became the staple in both military and law enforcement around the world. With the quad rail you can have a sight on top, a light on the side, a foregrip, etc. It’s perfect for adding all the goodies to the AR that you couldn’t add before. Coming to popularity in the late ’90s to early 2000s, the Quad rail was the best thing there was to replace that standard plastic handguard. The quad rail is probably the most widely known style of handguards, partly because it came out first. We have the great handguard debate for you. We decided that we wanted to give you a deeper look into the three most common categories of Handguards: Quad Rail, M-Lok, and Keymod. In that blog we mentioned that there are a ton of different options out there for someone to choose from.

A little while back we wrote a blog on How to change your AR Handguard.
