Save yourself the trouble for next time and just install one of the strike industries ultimate dust covers.
That is exactly what I'm hoping to install in place of the V7 I used in the initial build which refuses to stay closed.

I am not up on this gun, but can you give the front a good wack with a plastic dead blow hammer? may jar it ahead.

FWIW I purchased the Strike Industries Ultimate dust cover and it would not close on the FA upper (latest batch).

Cut in half, remove an inch from the inside, work back piece out, then use a punch on the barrel nut side and drive the other one out. It is a slightly undersized hole so have patience.
Cut it with what ? It's such a tight tolerance to the side of the receiver I can't imagine what to use to cut it without doing damage to the receiver wall.
Regardless, I'm at the point of no return now, the tension spring is mangled by trying to unwind it off the rod enough to get a grip on the rod with pliers to try tapping the rod forward....but the wire just broke and I can't get a grip on it any more to keep unwinding.....and I've dinged the receiver a couple times as the pliers slipped, cut right through the tape I used to try and avoid scratches.
Grrr
Man, that sucks. All I can add is to add a little heat to the pin bore most likely the back to try and get it to open up a bit, some penetrating oil, and maybe some side cutters in place of pliers to bite a bit harder onto the rod? I feel like the rod must have been pounded in all the way. It doesn’t need to go that deep into the bore, just has to clear the barrel nut. And don’t feel too bad, my receivers have gained a few scratches from assembling/disassembling. I use a sharpie to hide them a bit.
All that to install a sub-par plastic dust cover... maybe should have stayed with the original? ... or sent it back to ATTS and let them deal with it if this known issue is not a problem in their opinion.
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.

This is a design flaw that should have been corrected. ATRS was asked about it several times and according to them it is working as intended.

i had a little nub sticking out near the barrel nut. ended up using some old ones ( wrecks them ) and it finally came out.
Use a cut off wheel on an air die grinder or dremel. Slide a piece of shimstock in between it and the receiver if you can fit it.
May I ask what brand of rod you used ? Rod's tend to be 0.122-0.123", however there are a number of rods floating around that are 0.126, and I've confirmed with Aero Precision that their rod is supposed to be 0.122-0.123, but I've seen two now that were 0.126. The possibility of counterfeit parts did come up in that conversation.
I'm sorry you feel that way, however we do not see it as a design flaw.
But it is a design flaw. TDP for the US M16 requires a pin diameter of 0.125 with a variance of 0.002. Your channel is designed for a pin with a diameter of 0.122-0.123. AKA not in keeping with mil-spec.

All my pins BCM, Aero, Geissele, Colt USA, measure 0.125.
All our upper receivers from the very first to the ones we are machining at this moment have the dust cover pin hole sized precisely to 0.1250", verified using a precision gauge pin. The very schematic you posted clearly indicates that the pins must be 0.125+0.000/-0.002", meaning the pin must be 0.123" to 0.125". If the pin is smaller or larger than this by even 0.0001", the pin does not conform to the schematic you have posted here. A unilateral diameter tolerance of -.002" should be checked with a precision micrometer and not a caliper as variance in caliper measurement are too great to trust when the part approaches either end of the tolerance in question. We would be happy to measure your pins with our Mitutoyo Quantum digital micrometer, capable of accurately resolving 0.00005" (50 millionths of an inch), calibrated with precision gauge blocks to +/- 10 millionths of an inch at 21 degrees C.
Furthermore, our product is not an AR-15, M16, or variant of any of those rifles. It is our goal to produce a receiver that fits as many parts available on the market as possible, but we have no control over the parts created by other companies, nor does our product conform to any mil-spec standard as it exceeds them in many fundamental ways.
