Our rifles were getting metal fatigue and started to break ejectors. There were two kinds in ours, one was a large wide block that filled the whole bottom and the other had just the ejector on it with the rest of the block fixed. The later had the replaceable ejector but we had none since CAL had sold Blake Stevens all their small stuff. We'd used our up. If we broke ejectors it was a BLR and that rifle was gone. All part of the penny pinching of the '70s and early '80s.
