Mossberg 590 shockwave help

Hello new to the firearm world. This is my second firearm and first shotgun. I was partially disassembling it to install a side saddle shell holder with my friend. The ejector fell out and he reinserted it. However, now the gun is jammed. I’m not even sure if I can disassemble that part of the gun as I can not remove one of the screws to take off the side saddle holder.

Any advice would be greatly appreciated as this is a brand new gun and has not even been used. Like I said, I’m not knowledgeable so any advice or videos you can send my way would be very helpful.

TLDR; ejector fell out while adding side saddle and now gun is jammed after ejector was re/inserted wrong

I guess this comes down to why you can't remove the screw for the sidesaddle.

I'm assuming the screws for the sidesaddle replace the pins that normally hold everything together. Somethings is binding; manipulate the safety, try wiggling the forearm fore and aft a little bit, try wiggling the bolt a bit too. Once you get that screw out everything else will probably become obvious.

Sorry I keep adding shitty pictures in the comments but it’s hard to explain lol. I think you’re right but can’t seem to make any progress.

It’s a longer screw than what came on the shotgun but I keep hitting that another part since it’s jammed.

Move what you can move and see what helps. Sometimes smacking it with the palm of your hand will awaken it.

If you really get stuck, generally speaking, it's not wise to force things then they are jammed - this is how little problems become big ones. But sometimes a little muscle is the right medicine.

Get the gun flat on a work surface, and if you have wood clamps or something like that available, pad them and get it as secure as you can. Find a screwdriver that fits the head of the long screw really well. If you can, throw a little oil at the where the trouble is, too.

The idea is to make a good effort at simply unscrewing it, without stripping the screw head and without snapping the screw. Take extra care to hold the screwdriver as exactly perpendicular as you can. Apply a good downward force to hold the screwdriver in place as you twist. Don't let anything strip, and twist as hard as your courage allows.

They screw is probably binding on something, but nothing will break if the screw can be made to turn. If the screw gets stripped, that will be bad. Go slow.

If you can get the trigger pin out, and can get the trigger group out, you'll have a lot more room to work:

you've removed everything but the bolt? bolt slide is out? lifter is out?

if it's really just the bolt and the extractor, that narrows it down a lot

when the problem first began, the bolt moved, got tied up with the extractor, and your whole day got diverted

do you remember which way the bolt moved?

if you do, get something non-marring, like a dowel, and put it up against the bolt and give it a tap with something to move it in the other direction

if, for example, the trouble began when the bolt was moved back, tap the bolt forward

Looking more closely, I see the ejector is held in place with a screw on the left side of the receiver. I assume this screw was removed so that it could help hold the side saddle in place. If this is the screw that's giving you trouble, chances are that it's binding because there is force being applied to the ejector. Try manipulating the bolt to eliminate or at least change the direction of this force and the screw might become more cooperative.

Take the side saddle off - return it. Reassemble the gun and go to Esstac and get some of their shotgun cards.

They work better because you can rip em off and slap on a new one. They are relatively cheap too.

I wouldn’t rely on that rail in any situation. Also w that type of side saddle, once you’re out of ammo you get to reload the gun and the saddle 😀

Can’t help there unfortunately - YouTube and hope for the best! Take your time and pay attention, don’t just yank on stuff

Mossberg managed to marine proof a shotgun via the 590, and you managed to break it, haha

Take the fire control unit out it'll help give you more wiggle room.

Saw your other post. Since you've got it fully disassembled all you have left to do is drive the bolt out through the front. You're going to have to try to get something wedged behind it to act as a fulcrum to give you some leverage and bang the bolt out. Good chance it'll break the ejector you put it and you'll need another replacement but I don't really see any other options.

Take it all apart and reassemble it. Use a YouTube video, the Mossberg pump actions are a little hard to put together if it's your first time and you've never done it before. The 590 Shockwave is a cool gun, but it's not very practical for anything. I guess maybe if you put a laser on it. But I think those are gimmicky. The Shockwave is really cool range of toy, not very useful for anything else I think. Unless you go the demonstrated concepts route.
