Got my new RDB a couple weeks ago. Field stripped it, cleaned and lubed per the manual prior to fisrt shooting.
Went out today to shoot it for the first time. Got about 60 rounds through it flawlessly, then light primer strikes. After a few more of those I called it.
Got home, broke down the rifle and noticed that this part had drifted out a bit and bent, not allowing the rifle to complete a full firing action.
Already submitted a ticket to Keltec to send me a couple more of these pins. I wonder what is suppose to keep these pins from drifting out.?

This has happened before to others. Read this post:

http://www.thektog.org/forum/f119/broken-missing-extractor-pin-266669/index2.html

On page 2 I talk about using an AR-15 Extractor Spring Upgrade Kit to increase the amount of force on the extractor and extractor pin. Get a new pin or two from Kel-Tec and try the AR-15 Extractor Spring Upgrade Kit to see if it helps. Check your bolt carrier for any possible damage from the defective pin.

After removing the bent pin, the carrier doesn't look to be damaged from the pin very bad.
There is just a very small nick in the carrier where the pin was hitting it. Doesn't seem like that small nick would impede the function of anything.
Thoughts?

It should be safe to use but I would check the inside edge of the hole in the bolt carrier where the bolt goes for any burrs or peening that extractor pin may have caused. Use a small curved file to remove any burr or peened edges that stick into the hole past the wall of the bolt carrier to get a smooth surface. Get a new extractor pin ( I might try an AR-15 extractor pin) and then install the AR-15 Extractor Spring Upgrade Kit and you should be good to go.

Any update on your RDB running the BCM spring upgrade kit?
Looking at the other thread on this issue that you posted in, you were able to install the entire BCM kit including the O-ring.?
How many rounds through your RDB since you have done this? Looks like a good solution.
Wondering if adding non Keltec parts will void the warranty.?

I never had any problem with the extractor pin but I did put the entire upgrade kit in my RDB (spring, buffer and o-ring). I have put a couple hundred rounds through the RDB since then with no problrmd and no sign of pin movement. As for the warranty, just save the OEM parts for re-installation, if needed.

I did. Told them about the problem with pictures and I asked them to send me a couple through their website support tab.
It will be a few days before they even get to my message.
Glad I got all the right parts coming now though. Thanks for the help!

Shot my RDB today for the first time. Bought it about 3 weeks ago. Fired it about 25 times to sight in a red dot at 50 yards. Got home and checked the pin. It had not moved out, but could easily be moved out with a punch. I guess it's good I caught it when I did before it could do any damage. This is what I do not like about Kel-tec. Can't they send out a replacement pin that will not want to walk out?

I know what you mean...
Followed MarkB1 recommendation on the BCM spring upgrade kit and new extractor pins. Hope it will be flawless after that.

Should not have to use parts from BCM to fix a Ket-tec problem. This is a absolute joke. And please, nobody tell me I can ship my rifle to them because you think I am making to big deal over this.

Totally agree...
I just know that in my case they are going to send me a new pin and it's going to happen again. Or I send it back and they just replace the pin, not digging deeper to fix the problem.
That's why I am opting to get the needed parts and do it myself.

lol...agreed but you're going to have to clean your bolt anyway at some point...may as well install the upgrade. that or you trust in your expectations or lack there of and eventually have to send your gun in or not. again, i haven't had this problem but went ahead and spent the 5 bucks and replaced anyway. the extractor spring in the rdb pretty damn cheap. that extra tension with the o-ring and much better spring is much greater on the extractor pin to keep it from walking out. i mean take a chance and stay pissed on principle or spend the 5 bucks and never deal with the problem...it's your choice.

Good point HBeretta, I guess I did sound a little over bearing. Do you think you could just change out the spring to the heavier one and that would do the trick ? The reason I ask this is because the RDB just uses a spring from the factory, not a buffer and o-ring too.

Yes you could but why not also use the buffer and o-ring? The full set will give you much more force on the extractor to hold the pin in place.
