To the OP...
Another option you may not be aware of is that the MSAR E4 stock can be used, together with an MSAR trigger pack, on a Steyr AUG.
I have a friend who wanted a left handed AUG and also wanted to use NATO mags. Well, this is normally not possible.
I found out that you could use the MSAR E4 stock on an AUG so I bought a left handed AUG bolt for him. Then I took my AUG, threw the MSar E4 stock and trigger pack in it, along with the AUG LH bolt and test fired it with a Surefure 60rd mag jsut for extra fun. It all works! and it works perfect!. I am not the only one who has done this. It really works, perfectly.
It is absolutely sacrilegious, yes, but oh so AUGsome.
So try to buy just an MSAR E4 stock and trigger pack, or buy a complete gun, keep the parts you need and sell the rest. There is definitely a secondary market for MSAR parts.
