I'm building a beater AR. I have a nasty (all the way back) pre original assault weapon ban bushmaster lower that I want to match up with an A1 upper and 16" pencil barrel. Long Barrel commando, with correct handguards.
What allen-screw front sights work (accurately) with the A1 upper?
I only ask because I once read that there are different front sights heights between the A1 and A2.
