Expo Arms® AR-15 Quad Rail Handguard - 12.55"

For those that don’t know this is made by a small American Company. I won’t say their name because it will probably get removed but just know they have a good reputation in the AR community. This right here is a super quality rail for the price. The barrel nut is based off of a very well respected brands design. They then use their own locking system which they advertise on their website as being 17-4 stainless. This thing is definitely a stout well built rail. If it means anything I put this on a gun that is full Centurion parts minus this handguard. Will buy more of these

This was my 2nd choice next to the ~12.5 inch MI quad rail, but PA didn’t have it in the catalog. So I chose this and I’m very pleased with it. The material is sturdy, the barrel nut was solid and easy to install - only real complaint I have is that the lockup is 100% dependent on 2 small screws with no anti rotation plate. I haven’t put many rounds through the upper but so far so good with no major issues regarding the Handguard. As with any quad rail, this thing is heavy - keep that in mind when choosing a barrel (govt profile 14.5 barrel with a quad rail and a vortex Huey and this thing is heavy)

As previous comments have said the locking mechanism that they use for their barrel nut is the same as a very reputable three letter brand made here in America. However, contrary to one of the comments that I’ve seen this rail does in fact, have antirotation tabs built into the rail and does not use a “plate” which is much more sturdy in my opinion. Even though it’s a quad rail, it’s slimmer than most designs which was another reason I chose it, weight be damned.

Not many quad rails due to everyone wanting the rounded bottom hand guards. But this was the perfect fit for me and the look I was going for. Easy install and tool for the barrel nut made torquing an ease.
