I have a CMMG M4gery with a carbine gas system. It has the carbine buffer (3.4oz I think) and the AR15 carrier. I updated the bolt to a BCM with the black insert and extra strong spring and have had no extraction/ejection issues. I'm looking into getting an H2 buffer (4.6oz) and wanted to know how this one part change would affect (effect?) the ejection. Currently it throws all the shells at about 1 o'clock, which sucks for reloading. I'm looking for it to throw them at 3 to 5 o'clock like my 20" rifle. Thanks !!
