I've got 20", 16", and a 14.5" with phantom uppers. For some reason I want an 18" with mid length hanguards, seems like this would be a good all around length and look.

I could build it myself, starting with a undrilled 20" barrel, if they can be bought that way. Or should I just cut 2" off of a 20" and still have the long sight radius, but basically the same thing other than the length of the handguards? Your thoughts please.  

Some info here:

thanks, that's the kind of info I was looking for.

Hey, SPR is equipped with 18" barrel also!
