I run the bipod in the middle and i'm seeing roughly .2 mils of drop going to a tripod. It's very consistent and repeatable as well, so I am not too concerned about it tbh. There's a lot of variables that go into positional poi shifts so take everything with a grain of salt until you have a control group and can actually isolate the source of the problem. If it does become too big of an issue maybe geissele will have to redesign the handguard and barrel nut but I doubt that'll be anytime soon.
