I am looking at getting a lopro upper for a build I am working on which will be mounting an Olympic Arms FIRSH free flot rail forearm. I have heard from some people that the LoPro uppers have the picatinney rail set higher than a standard A3 upper, i.e. the rail on the LoPro would be slightly higer than the FIRSH rail.
Can you please confirm that the LoPro upper has its picatinney rail set at the same height as a standard A3 upper? Thanks!
