Amazon both sells things directly and lets other vendors sell on their site. MEGA Tactical is selling those through Amazon. I've ordered from 3rd party vendors (not Mega) through Amazon lots of times and had no issues.From Amazon? It said Mega Arms or something like that....
I have an ARMS rear sight that I believe is all metal. These said polymer blend? Same Quality? or is the metal version different? I'm looking to add a set of back up sights to a new build.
