inexpensive 10.5" AR pistol upper

[les snyder]

I've become smitten with the AR pistol phenomenon... but use a KAK SB-15 longer buffer tube (no castle nut, just reinforced shoulder)and no blade or arm brace, but it gives me nose to charging handle length... anyway, Palmetto State Armory (PSA) has a 10.5 complete upper with front sight tower and plastic hand guard for $200... an NC Star carry handle and you are in biddness...
