I bought mine from armalite.com I got the buttstock, handgaurd and pistol grip on clearance for $40 it was the advantage classic camo. I dont know if they have any more. I got it about 2 months ago.
I have a set. It has the grip, buttstock and handguard from armalite.
Make me an offer. It is brand new and came with a gun I bought from them last year. I can be reached at rwetton@nmu.edu
Thanks,
