Dean Posted March 22, 2023 Report Share Posted March 22, 2023 I have an rpb overstamp mac 10/9 for a host. 3rd time in 3 yrs its ran like shit. It wont eject the spent casing. Then fires out of battery. I pulled the extractor and it's fine. The empty case is so stuck in the chamber I almost cant pull the bolt back to release it. Could the barrel be defective and to small at chamber? Any thoughts? Quote Link to comment Share on other sites More sharing options...
chili17 Posted March 23, 2023 Report Share Posted March 23, 2023 Check to see if the chamber is bulged Quote Link to comment Share on other sites More sharing options...
Dean Posted March 23, 2023 Author Report Share Posted March 23, 2023 (edited) I dropped off at my dealer and he said the chamber/barrel needs to be reamed. Had this happen to a few Lage uppers. Edited March 23, 2023 by Dean Quote Link to comment Share on other sites More sharing options...
SBR Posted March 25, 2023 Report Share Posted March 25, 2023 Will Lage work on the upper? Switch out the barrel? Quote Link to comment Share on other sites More sharing options...
