Yes - once again, Im whoring central columbus for parts. My Ar15 has been probably diagnosed by my smith and we have fixed the problem, it was the PRI front sight/gas block installation, the set screws and the barrel were not 'seeing eye to eye' and it was bleeding gas. PRI is nice enough to replace the set screw model with their other 'simpler' model for me. Going to have to remove the phantom, and reinstall and do not have a spare crush washer.

Anyone got one?

IM me.  I have a couple dozen and can drop one in the mail tommorow.  I am in close to Xenia, so it shouldn't take to long.
