I have an Aero and it is nice and tight on their upper as well as some others.
I have some others that have no name that are just as tight but cheaper.
They all work and do their job.
Yep.
Name on the side of a stripped lower makes very little difference. They are as close to a commodity as exists in the AR market.
I use the price of stripped lower as my barometer for the overall price level of the AR market.
