Geissele rifles & uppers.

You can get better for the same money, or less IMO. They may be there someday but not now

What manufacturer specifically and what makes it better?

Meh… The Geissele BCG is interesting but nothing else about the gun interests me or stands out. IMO, LMT and KAC are where the innovation and improvements are.

Realistically, the only real advantage KAC has is the ambi-lower. gas system, improved bolt, handguard interface...other then price there isn't really an advantage. Not to mention KAC recently enlarged their gas port on the mod 2's, so one could argue that Geissele's gas system is superior.
