I've been looking for the right barrel for me.  I really like the sound of the Noveske N4 barrel, which I understand they don't sell by itself.  Is there one that is comparable?  I'm looking for a 14.5" 5.56, 1:7 twist chrome lined that is fairly light weight.

Also I was wondering if anyone knew who makes the Noveske N4 rails?  Do they make their own or are they purchased from somewhere else?  Thanks.

RRA R4 lightweight is extremely light and chrome lined. Available in 1/7 twist but not sure about 14.5

Barrels are sold here:

Rails are made by these folks and lots of sellers stock them:

Thanks modus...looks like you can't actually just buy the barrel, but at least it gives me some more options.  Does anyone know of any barrels that would be similar to the noveske?
