I don't recall seeing one like that.
Contact Keltec, and get a return order.
Oh, I forgot, they usually shut down this time of year, and open up in January. But I would still shoot them an email with a picture.
KT will gladly fix your broken Sub2k. Get in touch with them and they will tell you how to send it back. Unless you live in some Commie state you can ship it to them and have it returned directly to you. Check your local laws.
I've been holding my tongue on this thread, waiting to see if the OP was going to better explain the circumstances of the failure. Since that hasn't happened, I can't help but speculate that this was operator induced disassembly/assembly error.
That part of the hinge serves as an assembly index for the square locknut washer (part 404) and the two halves of the forend. Once theses parts are properly assembled there is very little force that is exerted on that portion of the hinge. It is not part of the latching function of the hinge.
So the two possibilities for the failure are:
1) a flaw in the injection molding of the hinge or
2) gross user error when working on the gun
I am leaning toward the second choice in lieu of more information.*
*Of course this is the internet and while I have no experience taking this part of the Sub2k apart, that doesn't stop me from shooting my mouth off.
OK in Lou of more information, here you go !
#1 purchased the weapon knew .. Took it to the range roughly around 75 rounds the front site came loose , Took the weapon home to retighten the front sight .further inspection showed a major scoring mark on the end of the barrel from the setscrew, realigned and tighten .
#2 I went back to the range the following weekend to re-zero the front sight, At about 225 rounds I noticed the barrel would rock up and down well over an eighth of an inch and that stock forend would spin.. I thought that this was unsafe and stop shooting the weapon and took it back home .. after further inspection you can see in the photo as to what I found ...
#3 This weapon is 100% stock and did not even have an initial cleaning at this point .. I must say that the weapon straight out of the box ran 300 rounds without one FTF or FTE.
It is a pain, but given the two issues I would send it back to Kel-Tec for repair. Most likely they will replace your front sight with an upgraded version that does not use the set screw and replace the hinge.
OK update on the sub2000 with 300 rounds on it and a broken hinge !
1. I contacted Keltec and they informed me to send the weapon back for repair .
2. I sent the weapon back at the tune of $22 for shipping, not bad .
3. I received a weapon back yesterday after 2 1/2 weeks and I was informed that they replaced the barrel and test fire .. OK .
4. After inspection of the weapon it appeared that the barrel was not A new barrel . It appeared what was either used or a reconditioned barrel , What I found was a set screw Mark at a 45° angle on the left side of the barrel from the earlier version of the front sight also you can see where they did a touch up bluing job around The set screw Mark. "See photo"
5. Now I'm wondering how many rounds have in the fired for this barrel ?? 5,100,1000 or more ????
6. I will be calling them back today with lots of questions and I will update you when I hear what they have to say , so for now be aware of what you're sending them and what you're getting back !!
Calm down. Your worrying about nothing. First that little Mark could be caused by any number of things. Look at the barrel. Is it beat up, bore damaged? No... go shoot the dang thing. The rest of the gun will give out long before you wear that barrel out even if it did have some use, which I doubt.
Hey this was a brand-new gun that broke after 300 rounds ! I sent it out to be repaired and it comes back with used parts !! That's Not acceptable in my book ! That's OK if that is the way you like to keep yours guns ? I like mine to be pristine .....
I have never known Kel-tec to replace broken parts with used ones. Looking at the picture I can see a light spot in the bluing. I have no idea whether it is a repair or not. Kel-tec is not known for having very deep bluing in any case. When they do replace a barrel they replace the entire assembly, not just the barrel. Everything from the pivot block forward is new with the possible exception of the forearms. How do I know this? I bought one from them several years ago and specifically requested that the front sight be deleted. Didn't happen. They reached in a parts bin for a replacement barrel and I got everything from the pivot block forward except the forearm. If you're not happy with what you got back take it out on Kel-tec. Call them and give them the opportunity to correct it or not. Do not take your frustration out on the membership here.
