I am in the process of building a M16-A1 kit. The front sight group was already attached to the barrel, so in order to attach the barrel to the upper I either have to:
A) remove the front sight group to use the Brownells barrel nut wrench for $25. Probably the strongest because it is a full 360 degree wrench
or
B) Buy the Spikes Barrel wrench the will slip over the barrel for $40.
or
C) Use my armorers wrench. I have heard that these sometimes have a tendency to break. I thought I bought a good one, but who knows.
What do the rest of you use? (I am leaning towards the Spikes)
