Long post… sorry
I had some issues with my Sub 2000 field stripping it. I struggled with it when the M-Carbo recoil spring would not come out. It was stuck in it. I took it to the range that I go to regularly, but their gunsmith said to contact Kel-Tec which I did. They instructed me to send the firearm to them with documentation as to what the problem is. This is what I sent them…
I spoke with someone in your rifle technical department on March 30, 2022 about an issue I was having with my Kel-Tec Sub 2000. He recommended sending it in with a description as to what the issue is.
I had informed him that some modifications were made with M-Carbo parts, but none were internal such as the hammer, or trigger. The only internal change that I have made was swapping out the recoil spring with the M-Carbo spring in order to install their Recoilless Charging Handle. The M-Carbo spring has a locking pin that inserts into the handle.
I have used the Sub 2000 almost weekly since purchase with zero incidents with field stripping in order to clean it until recently.
1) Three weeks ago I field stripped it and had a hard time getting the bolt and bolt head to slide through the receiver and drop out. Then it was challenging to get the bolt head to reengage when reassembling. Once together the charging handle worked fine.
2) Two weeks ago it shot fine. But when I field stripped it I ran into similar issues with the bolt and bolt head getting them out. When I lift on the charging handle it seems as if it is binding on something at a certain point. I was able to get them out and did a good cleaning and even attempted cleaning inside the receiver tube. Afterwards it was hard to get everything to drop into place, but once it did the charging handle worked fine.
3) One week ago, again it shot fine. Probably 150 rounds through it with no issues. This time after I pulled the stock off and lift the handle again it binds at a certain point, but now I can’t get the M-Carbo recoil spring out in order to remove the handle to even attempt a cleaning.
It almost feels as if the receiver tube is smaller inside or the bolt or bolt head are swollen. I know that sounds ridiculous, but I’m no gunsmith. Hopefully it’s not a big deal.
All my information is at the top of the letter. Contact me for any further information. Appreciate it.
I received it back today. On their Repair Work Order these were the notes:
- Disassembled, cleaned & inspected
- Repaired M-Carbo locking pin (Recoil Spring Assy). - NOTE: I had to file a large burr off the locking pin stem. I suggest checking during cleaning/maintenance and after every range-trip to make sure it doesn’t happen again or worsen.
- Replaced damaged Left & Right Forends
- Reset Front Sit Assembly
- Reassembled & test fired
- NOTE/HELPFUL TIP: Use a 12g Bore Mop to clean the Bolt/Tube Receiver after every range-trip and keep the Bolt/Bolt Head combo lightly coated in a lubricant/protectant i.e., Lucas Oil CLP)
I haven’t fired I yet but decided to field strip it to see how it was. As I slide the M-Carbo Recoilless Charging Handle back it still binds. To top it off, I have the same problem AGAIN. The Recoil Spring will not come out. I can tug and tug on it. It is jammed in there. That’s why I sent it to them. The picture below is as far as it will come out. Wonder if they were able to remove the spring, clean it, get it working okay. Then they test fired it, but didn’t try to field strip it again. I’m thinking after they fired it, the issue repeated itself.
Any thoughts on how I can get this spring out?
Should I buy another Recoilless Charging Handle/Spring (which was a pain in the ass to compress to get the locking pin on)?
Should I send it back to Kel-Tec?
