Excellent deal on 6-pos stock
 

Brigade Quartermasters has Tapco ACU (foliage I'm guessing), 6-position, collapsible buttstock assemblies on sale for $24.95. If you have access to BQM through AAFES, the buttstock assembly will be $22.45 with free shipping if the order is over $40.

I believe the Tapco's are commercial diameter receiver extensions, but they are a good quality commercial, in my experience.

Hope this helps those trying to put together a lower for a reasonable sum.
