sadly my friend, that NEA stock won't work with my upper, the NEA has a proprietary bcg not compatible with my 9mm bolt, that stock was my first choice!! but after looking into it, I was told no sadly.
my second choice is this, LWRC UCIW
not too shabby either, the buffer that came with this LWRC stock won't work with 9mm either but there is an aftermarket replacement buffer for this stock, or I could use a H3 buffer so I was told.
