I came across this site in my travels, and thought I'd pass it on:
They have new, in wrapper, triangle handguards. They seem a little high in price, but I haven't seen them around still in the wrapper.
I also noticed that they have a few M-231 stock adaptors, new in wrap. I did see the wire stocks somewhere else, maybe Gun Parts (Numrich). This is for the port-firing weapon. I haven't seen anyone make a clone of this yet; it might be interesting.
Just a heads-up.
A lttle high? How about bloody outrageous? I've bought new triangle guards off the EE section of this website for $10. No; not in the wrap; but if they're going on a rifle, what the heck is the wrap worth??
