I don't know how this happened but I was putting everything back together after doing the trigger & trigger spring upgrade and then I notice the ejector was poking out on the other side a little bit through a bulge in the plastic(see attached photo), I hammered it back down into place with the blunt side of a metal punch and then I cocked it with the charging handle and it was sticking out again. The bolt looks like it's in place the normal way so I don't see how it could be hitting this on the way out.

It seems easy enough to replace by getting another grip assembly for $50 from Keltec but what can I do to prevent something like this from happening again? I did have to keep readjusting it a lot to try to get it to go into the right spot as I was putting everything back together since it was completely loose when everything came apart, so I guess it's possible that maybe it ended up in the wrong spot? Or did I install it backwards? I have the long curved part facing towards the barrel and the short flat part facing towards the bolt because that's how it looked in MCARBO's installation video but now I'm noticing a small scrape mark in the bolt head and the bolt head feels like it's hitting some plastic or something as it reaches battery so maybe it is backwards. :/

Also, would it be safe to fire like this in the mean time? I'd guess that I might possibly be getting some FTEs from it not being all the way in like it should be but it looks like it's not near anything pressure-bearing when the gun is in battery.

I'm no expert, so I would send that back or get a new grip. I don't see how it could do anyting but get worse from there.

Lost my post. Looks like you assembled it incorrectly.
Extractor faces inside bolt tube/receiver. Do not shoot it. Take it apart and try again. Got pics if inside the tube?

 

[3wbdriver]

You installed the ejector fin backwards in the receiver. The fin is supposed to face into the receiver area and the flat base goes between the tube and grip side, and rests on top of the magazine when one is installed. If you pushed it back in with a punch I'm guessing you've caused more damage, either to the tube or the ejector. This in addition to the damage already done to the grip half.

And the short fat part goes toward the barrel. That is what catches the back of the spent case to force it out of the port.

 

[VegasSub2K]

You need to send it in to KT. I am sure there is more damage.

 

[j5689]

Yeah I'm probably going to order a new grip assembly then soon and swap all the internals out whilst of course installing the ejector the right way this time. If the bolt head seems particularly damaged I'll replace that too. Definitely not firing it until everything is fixed, it doesn't feel/sound like it's going into battery properly. I notified MCARBO that it's the wrong way in their instruction video too when they reassemble it which is how this happened.

 

[haugrdr]

Not positive...but I'm pretty sure I read that KT isn't selling just the grip assemblies? Anyone know?

I think this was to keep up with production, but it might be due to some ATF scrutiny. In either case with the damage to this one I think they might be convinced to sell him one. If not, he'll just have to return it. Which I would recommend anyway, not knowing what additional damage may have occurred.

I will say it is nice to see Kel-tec finally identifying what magazine the receiver fits stamped on the side. That was a major point if confusion on the 1st Gens.

 

[TSB]

KT shows them in stock @ $50 for the pair...

 

[j5689]

Yep right here:

https://www.keltecweapons.com/quickview/index/view/path/s2k-410-l-r-grip-903

The serial is on the bolt tube and not the receiver(which the grip assembly kind of functions as in this particular rifle) like many guns so I don't see why they wouldn't want to sell it as a replacement part, especially when apparently all it takes to damage it to the point of being unsafe to fire is installing your ejector backwards which is very easy to do given that it fits into the bolt tube and the left side of the grip the same way regardless of whether it's facing the correct direction.

But the ejector doesn't go in the same way. I would understand if you reversed the fin facing by accident, but you installed it with the fin not even inside the tube but facing out to the side of the receiver. If stood on its base the ejector in the Gen 1 looks a little like a shark fin and the tallest part faces the chamber in the barrel. The flat base goes into a recess in the grip half and the tube goes over the fin via a slot and holds it in place against the grip half. I'm virtually certain the Gen 2 is the same way, although I personally don't own one to confirm this.

As far as it being very easy to damage, in over 10 years of membership here yours is the first I've seen do this. Kel-tec's intention with providing replaceable grip halves was to ease transition between magazine manufacturers. NOT so people could more easily replace parts because they reassembled theirs incorrectly. I understand you're upset about the damage but please don't blame Kel-tec for something they didn't do.

My fin was installed facing into the bolt tube actually, it was just facing the wrong way inside the gun like you said, give me a little more credit than that, lol. It's more the fault of MCARBO for installing it backwards in their gun in the instruction video which can be seen here when he reinstalls that part at 12:15. And then if you look closely on their one-point sling page, there's a picture of that gun with the same damage as mine had from them installing it backwards with the ejector base poking out of the grip:

Every thing else about that instruction guide was solid except that part, I should've looked at multiple sources but I figured they knew what they were doing so I intentionally copied the orientation of the ejector from their video in a hurry just to get the darn thing back together again.

I don't care too much either way, I just ordered the new grip yesterday and then I can replace it and have this all together the correct way. Just very very frustrating

Yeah, that pic looks like the same punch through as yours.

Maybe reach out to them and let them know what they've done.

 

[850sub]

Awe smack! Give the man some cred.

 

[j5689]

I did, the person in charge of their help e-mail gave me the impression that they didn't speak English well so I'm not expecting much in the way of good communication. They said they were sorry I had problems and they would pass my message onto the team in charge of the videos. Then I got what appeared to be a followup e-mail from somebody else there (I don't know if it was related to my initial e-mail or just a general friendly personal followup for all customers) making sure I had everything I ordered and somewhat ironically linking me to a page compiled of their instruction videos.

I suggested they add an annotation to that part of the video warning people to install it facing the correct direction but I still don't see anything like that in the video yet. So I suspect many people have already done or will do what I did if they didn't pay attention to the way it was originally oriented from the beginning and they'll either just keep it as it is once it's damaged, which is potentially dangerous, or spend another $50 replacing the grip and doing it the right way like I'm doing. Hypothetically in the case of a Gen 1 installation, they might actually be helpless to replace the grip since the serial number would be on the now-damaged receiver. I don't dislike MCARBO, they clearly make good products for what is, in my opinion, an underserved aftermarket and they seem to have good intentions but it's not right to let something like this go uncorrected

 

[TSB]

No need to worry about this happening to a gen1. The ejector is not removable like in the gen2. It is part of the metal serial plate that's molded into the receiver.

Were you able to reinstall the ejector facing the right direction, or did it also get broken in the process? I didn't see a replacement ejector listed on the KT site.

 

[j5689]

That seems like a much smarter design than what they did for the Gen 2 but I'm sure there's a reason for everything. I like the serial being on the bolt tube but I think the ejector should've been permanently mounted somewhere.

Yeah I didn't see a replacement ejector there either but luckily I don't think mine is damaged at all, just some paint missing. I'd be more worried about where it's making contact with the bolt head but it's pretty much the same case, just some finish missing.

I haven't actually attempted opening the gun up and switching it back around yet, I've just put the gun out of commission and I'm going to wait till I get the new grip assembly first and then swap everything over whilst installing the ejector the right way so I'll have a nice new receiver with no holes on it that don't belong there. I'm supposed to be getting an RDS for Christmas too so I'm waiting on that anyway before I fire it again, whether I've got it working safely or not. The recoil constantly kicks my earpro muffs off at the indoor range from having to get so low on it to get a sight picture so I basically need a high-sitting sight or it's dangerous for my hearing to fire it, I'm like 25% sure I got hearing damage the last time it happened.

Everything else about that instruction guide was solid except that part,

Nope. Not even close

.
Compare the position of the trigger return spring during disassembly at 6:24 and the position it is in during reassembly at 14:15. Which one is right?

Assembly is finished at 21:49, notice the trigger guard position <EDIT while it is completely disassembled and correctly reassembled> and the operational check at 21:51 when it magically is healed.

Two people that shouldn't be working on guns:
Me.
And that guy:laugh2:.

Some things must be put together 100% correct the first time.
Simple mistakes like that can get people blown up.

Here's a suggestion:
Take 2. Roll camera! ...Action!

 

[j5689]

Yeah you're right, that makes me wonder now but I can't see any other reason for that little extra piece on the trigger bar if not to add tension to the spring and keep it one place while being assembled, as opposed to leaning it on the pin like that, although it doesn't explain how it got that way. I also noticed the loose guard initially, and he doesn't actually show how to put the tension back on it, he just has a YouTube annotation around that time saying that their other vid shows how to do this, which probably has something to do with the fact that the guard is loose at first when it's back together, it's not actually tensioned because he forgot to do it. That whole system is not even an issue if you lock the barrel forward first before you start dissassembling the gun, you can freely take the barrel out and put it back in once everything's apart without ever having to mess with the trigger guard. He did it while it was folded up and it only caused more issues. What a mess that video turned out to be

 

[BlakeHanson]

...What a mess that video turned out to be.

The ejector error not withstanding...
While I am not one to cast dispersion on people that do things I can't (maybe they are listening), the white background is the worst possible to video a black object and hope to see any detail. It closes down the aperture on the camera.
Most GB people use a green felt, red felt or navy background for their pictures of black guns.
It makes a difference. Which ones of these can you stare at details on?
