Selling a few of my toys to fund a new house, so my SOPMOD Block II m4 upper is up for sale. It is in excellent condition with less than 1000 rounds thru it. Upper assembly done by ADCO. Here are the specs:

Upper: Factory LMT complete 16" upper, fsb shaved by ADCO. DD RIS II FDE Rail, Surefire SF3P Flashhider

KAC 350m rear sight and KAC Taupe front sight

I'm asking $900 shipped for just the upper, $1150 for the upper with the KAC sights.
