I have a Norc M4 on the way and want to order a Magpul stock for it but I do not know if the buffer tube is Commercial or Mil-Spec, any assistance is much appreciated.

Thanks
Steve
 
It is slanted at the end.
I think it is a commercial tube.

That is a general rule only, there are exceptions.

I have a commercial size tube without the 5 degree taper on the end. Unknown manufacturer.

Also, Double Star makes a military size tube with the 5 degree taper. It is also longer than mil-spec. So when a stock is assembled to it, either you can't collapse it completely, or if you can, there is some tube sticking out from the buttplate.

Don't buy junk like this.
