Hi there,

I'm going to build a new AR, but I have a simple question that I haven't been able to find a clear answer for. I'm debating either a CAR or M4 build, but I can't quite find out how long the M4 handguards are when compared to the CAR ones. I am going to put some YHM handguards with rails on it, but if the M4 handguards are really short (not having much room for accessories), I might go with a CAR build.

Does anyone have the measurements for the two?

Thanks a lot!

They're the same length.

Well, now, don't I look silly? Ok, that makes sense. Are the M4 ones typically a different profile or something? In most pictures they look different to me.

So I can buy CAR style handguards and put them on an M4 upper, right?

They're interchangeable. The difference is that proper M4 handguards are a bit wider and have double heatshields while the standard carbine handguards are narrower and taper a bit.

The YHM carbine length handguards will fit an M4 upper.
