I apologize for not posting in an existing thread about builds, but I'm about to have a tantrum and hope someone can offer some insight how to get the ejection port cover rod out of my MS upper.

Handguard is off, barrel nut is off.....but I can't get that damned rod to move out of the upper.....there's nothing to grab onto, no way to tap it out forward from the rear etc. I've tried using a utility knife to "twist" it forward, a toothpick to try to get it to move.....lots of swearing, that didn't work.

All the Youtube vids show how to remove it from a traditional upper with open detent holes on both ends, but these MS only have one open end, so it can only go one way.

Anyway, if anyone has a trick up their sleeve, I'm all ears.

Thanks
 
No c-clip, not needed on the MS as the rod is captured by the barrel nut, and hand guard.

I've Youtube'd the crap out of this, trust me, I didn't want to ask for advice. But everything I find is a demonstration based on the AR-15 platform, which allows a punch/drift tool to be used on either side of the port rod....the MS only has one way to move the rod...towards the front of the upper....I can't figure out how to get that rod to move, there's nothing to grab onto or tap.
 
You may have to cut it. I’d try grabbing the rod wherever possible with needle nose pliers and tapping them with a small hammer (or a punch works well for tapping) to try to get the pin moving. Will depend on the style of cover if this is even possible. Squeeze the heck out of the pliers to get them to bite. Best of luck.
 
It's the long weekend so the folks at ATRS might not be checking CGN. I'd send them an email and wait for their response before doing any cutting.

Thanks buddy, will try a bit more brute force option at this point, was hoping there was a more elegant solution. Trying not to scratch the receiver, but my impatience is getting the best of me.

Yeah, I figured it might be a slow weekend to get input. Just got a bug in my head to make a couple adjustments to the rig, now it's half torn apart lol.

The Geissele Super 42 braided buffer spring was installed in probably less than 5min, the dust cover has eaten up about 5 hours.
 
I just open the dust cover and come in with a Olaf knife and carefully not to cut my self ,come in beside the spring and and cut into the rod and pull forwards till I get enough sticking out to grab with pliers

The MS hole for the dust cover pin is undersized, or at least my buddies was, it would not accept a standard size dust cover pin without a lot of encouragement, needless to say that thing is never coming out in one piece again, cut in several pieces... maybe.

Kind of the idea I had early today....but the port rod I used when I built it is titanium...it's being difficult to cut into...I'll give it another go tomorrow when I'm more patient.

Would be the last resort....starting to cut stuff apart is my least favorite preference, I can't see how my upper doesn't come out of that exercise without looking like it was chewed by a dog.
 
not sure what else to try ,maybe pull out the spring and its fine enough it should unravel by pulling on the long side and should give you enough space to get a decent area to use pliers to pull rod forwards ?
 
Before you cut it, you might be able to somehow cut a small slot on the body of the rod(assuming the springs are cut away). Insert a flathead and start hammering it. That way you may still have an intact dust cover. It's all theory though I've never tried.

Well then I would try the vice grip method and tap tap tap with patience like Uisge said until there is something to grab onto by the handguard end... that may also be impossible with a titanium pin/rod... personally I might consider just leave it alone with the dust cover already installed, honestly this may be a one time install only receiver.
 
good pair of needle nose vice grips ( vice grips ... not pliers). get a good lock on the end where you took the hand guard off, and tap on the vice grips with a hammer?

Question if it is tighter than a S.O.B to get it out.. then was it tighter than a S.O.B to get it in when you installed it ?
Asking for a friend.
