Alright new to AR308s (But not ARs) I have a Windham weaponry "308 Hunter" with a mid length gas system that came with boyd's wood furniture and will take magpul furniture if you trim the heat shield , I just picked up a McGowen .338 barrel and went to put it on but it seems the gas system is shorter on the McGowen barrel and wont allow the magpul or boyd's furniture to fit. The McGowen barrel uses a normal AR15 mid length gas tube but the Windham gas system/gas block seems to be .297 further out on the barrel. My question is, is there list of who makes the longer mid length barrels / gas tubes to fit normal handguards? other than Windham.
