Carbine ejects to forehead

[DaveHH]

If you are going to change things around and try different combos, you might try the original extractor and make very sure that the plunger is installed correctly. This could have been the original issue. A lot of carbines have the plunger facing the wrong way and not resting on the extractor shelf. The ejectors themselves have some effect on case flight but it isn't as radical as one would expect. I've changed from a type 1 to a type three and noticed no change. Then from a 3 to a 2 and it solved the issue barely. Having the carbine well lubricated has some (actually a lot of) effect as well. I put a lot of grease inside the cam area of the slide where the bolt lug lives, this makes things a lot smoother in operation.

Received the type 3 ejector (flat face) from Bill Ricca. Replaced the type 2 slide, original extractor and the type 3 ejector. Fired 15 rounds all of which ejected at 4-5 o'clock. No failures of any type. The type 3 ejector's the answer. Dennis

I agree with you regarding greasing the op rod guide lugs and cam areas. The carbine op rod is notorious for wearing particularly at the rear tab. This is the most frequent cause for replacing the op rod. I've found, instead of replacing the op rod, having it rebuilt. Greasing the channel significantly increases the life of the op rod. Grease is your friend. When I started working on this carbine, there was no grease. I did grease everything when I changed from the type 1 to the type 2 ejector and as I mentioned, it didn't change the ejection pattern. I then changed the extractor and the type 2 op rod for a new extractor and a type 5 op rod and this did change the ejection pattern to 3-4 o'clock. When I received the type 3 ejector, I replaced the extractor and type 5 op rod for all the original parts with the exception of the new type 3 ejector. The ejection pattern remained at about 4-5 o'clock for 15 rounds. Maybe it was the grease.
