This happened to me yesterday and I'm not sure how. I realize the manual specifies proper assembly and disassembly, but I'm also aware that this can be a common occurrence especially on the ar15 side of the market. I called kel-tec the day after and they immediately sent out a replacement.

Total round count?

Sheesh...! Sorry that this happen and I know Keltec will make it right, but what's next?

 

[HBeretta]

i understand it happens but the concern is no aftermarket support which is obvious. but when something like this happens you can only wish. i mean in a perfect world...tungsten or titanium firing pins stock would be a dream come true.

 

[c13urge]

Aftermarket part will come, hopefully. But Keltec is good about fixing their issues...
Thank goodness for that!

It looks like you activated the Two Part Warranty. If your firing pin breaks, you get to keep both parts.

This reminds me that I need to order some Just In Case spare parts. I was waiting to see if a consensus develops about whether it's better to get a Kel-Tec RDB extractor pin or a quality aftermarket extractor parts kit for an AR.

I like to have small replacement parts for my guns, for the items I'm most likely to break or lose. Kel-Tec is great about providing these spare parts at a very reasonable cost, and their website now makes it super simple to place an online order. I have spare parts for my PLR-16, SU-16, various SUB-2000s and SU-22. I need to put together an order for the KSG, CMR-30, PMR-30 and RDB. Let's see. Did I forget anybody?

Resurrecting this older post as I had a firing pin fail over the weekend in the exact same fashion.

Had ~1,200 rds through the rifle and must have had the failure in between range trips, as I experienced the failure on round 1 (i.e. "click not bang") over the weekend. Ejected live round, no dent on primer and almost immediately knew what was up. Tried round 2 just for good measure and of course the same.

Thankfully I had the foresight to request a spare firing pin in the past and actually put it in my range bag. So the day was not all lost.

As usual, a replacement is on the way at no cost (basically a spare for the spare, thanks, Ericka!), but I also asked if there was any particular reason a few of us on the forum here experienced this. Quoting Ericka: "As far as I know, a batch of pins were messed up in heat treat, but not caught until some had already shipped, so the new ones I am sending you should be ok."

My serial is Z06XX. Wondering if the others with failures are in the same serial number neighborhood.

Mine broke after 5k.

Mine broke today, only 300 rounds in. Z0ZXX.

Holy smoke - 300 rounds???? What gives on this and I’m wondering why this happens. I don’t have a lifetime round count but it’s high and I’ve never broken a firing pin on anything so I’m having a hard time making sense of this.

Yeah, I'm concerned too.
Seems a bad batch of hardened firing pins are to blame. My PMR-30 got to about 2500-3000 rounds before it broke. And I wasn't happy about that.

Firing pin failures in the RDB platform are very, very rare. Less than 1%
So I'm not so worried.
I have the factory warranty. KT has been good to me.

My first broke at 800 rounds. My current one is at 1200 rounds now, but the tip is missing a tiny chip. I have a spare, but my current one is definitely going to break as well.

 

[IamScotticus]

I haven't shot enuf rounds to break it before other stuff broke.

First trip to the range with new RDB-C. I was sighting in, adjusting the gas, trying different mags, and trying different ammo. Since I was experimenting, I never had more than 5 rounds in mag regardless of mag size (yay Freedom Week!). I suspect I was less than 100 rounds and then it goes click. It goes click 2 more times and then I look at the cartridges. Not even a mark for a light strike. Came home and took it part. I seem to have a broken firing pin. I really hope it's a bad heat treat since this was pretty disappointing for the first trip out.

Here's a pic of a couple spent cases and the three that went click. Not a scratch.

I dont have a spare firing pin, but I will. I'll open a case with Keltec and then maybe order extra on my own. I'll only report back if their service is unusual or a new pin breaks too.

What serial range is your rdb? Wondering if this is an older model.

What serial range is your rdb? Wondering if this is an older model.

I had assumed that since it was an RDB-C that it wasn't a particularly early one. The first three characters in the serial are Z3G
