Hey Gtek - No - not another lower "Yet" - but will try if other checks on the bolt carrier and the magazine check out. Also the Ejection port and the clearance therein have been opened even more than standard - with a custom deflection ramp as well. I shoot lefty and the casings do fly out slightly forward - The clean ejections (when they dont jam) to us seem to be a result of the fact of being under gassed or the buffer being too much. We have tried a multitude of springs in combination of a few buffers. However the multi-adjustable custom buffers are the next item. And again - its port is maxed opened for gas.
Will be able to break it down tomorrow a bit further as my house guests are leaving tonight. Thank you for the suggestions...
