98Z5V Posted August 22, 2019 Author Report Share Posted August 22, 2019 Ejectors. Feeding problems. Some ejectors just suck. We've touched on ejectors being a problem here, but just in random threads, trying to diagnose feeding problems. Here's a great picture that tells the tale on it all. "Squared off" ejectors will piss you off, make your gun a jam-o-matic, and you'll play hell trying to figure out why you can't shoot more than a couple rounds without a misfeed. Look at your ejector face. If it's a squared-off ejector face, you will more than likely have a feeding issue, and it will always be the round that comes from the right side of the (double-stack) magazine. Period. That's the whole story, right there. That round that comes from the right side of the magazine will have to "slide over" and it's gonna hit that square-faced ejector, and cause you some feeding problems. Round that bastard off, if you have a square-faced ejector, and you have feeding problems. I'll bet you that it fixes your issues. I can describe how to do this, and it's easy. Check your gun-function, but then check your ejector closely, and see if this pertains to you... Here's the pic - it explains it all.

98Z5V Posted August 22, 2019 Author Report Share Posted August 22, 2019 "Square-edged" ejectors also rip up your brass, and leave some nasty "ejector smears" that result in sharp "deformations" on the case head on your brass - that's the first clue, if you never looked at your ejector. That all happens during the "extraction process." That bolt rotates during unlocking, and that square-edged ejector will tear up your brass on an overgassed gun or an under-recoiled gun... That's important, if you're a reloader. You now have to deal with filing down that brass, just to get it in a shell holder. That's just something else to look at, if you're having reloading issues, and just getting that brass into a shell holder... If you've seen that on your brass - look at your ejector face, first... This pic was titled "Reloading pressure signs..." There are no signs of excessive pressure on these two rounds. But... there are definite signs of a squared-off ejector causing this brass damage here. Nothing more than that... That ejector was SO square, that it made a full circle on that case. If it was radiused or rounded - that would not appear like that on this brass... *** FULL DISCLAIMER HERE - I'm not a Certified Gunsmith, so I might not know what I'm talking about. Since I'm not "certified," - use my info at your own risk, then go to a "Certified Gunsmith" about your issue, and see if he even knows what I'm talking about. Chances are, he might not have a clue, on AR Platforms... Thus Endeth the Sermon. Quote Link to comment Share on other sites More sharing options...
