KEL-TEC SUB-2000 Integrated Tool-Less Locking Pin for Aftermarket Charging Handles

Charging handle won’t lock back . Installed original an works fine . Reinstalled an same problem . They said they sent a response. I can’t see it because says password is incorrect. Did that 5 times already!!!!!!! Pissed

I of course didn't read the instructions/watch the video and said the same curses that everyone reading this did. Compressing an oily spring under compression using only your hands WILL remove skin and maybe an eyeball - here's how to work smarter not harder:

* a 3/8" deep socket in a vice holds the spring nicely. If you don't have a socket set, back away from the weapon and find someone who does.
* get a paperclip, it will help prevent "pushing" the freed link into the captured link.
* compress the spring as shown, insert the little hex wrench, and bend the papercip into a tight U below the hex at 90 deg to capture the upper loop.
* Thread the spring down the hex/paperclip into the compressed captured end in the vice - screw it down like a bolt.
* once tension is off the top spring keeper, swapping in the new improved part is cake.

I spent 10 minutes cursing, pooped a beer and then it took maybe 45 seconds using this approach.

I tore all the skon off my fjngers pulling the speing back over and over and trying to insert the pin to hold it back. Had wuite the time but i fjnally got it. I cant help but assume it would have been so mivh easier if I had one of the blocks to hold the base. Once ready to go in the weapon I do like how it is so muvh easier to get the charging handle to stay in. Makes assembly muvh quicker.

If the tool pops out you are totally screwed. Now I have no idea how to compress the spring to get the locking pin in. I am really wishing I had not attempted to use this pin

 

Used a caulking gun to compress spring. Also used bolt from gun to keep spring straight.

This thing was a pain to install. What I did was lock the Allen wrench between the two wires and then twisted the spring like a bolt. The Allen key holds the tension in place so you can work on the other end without having to compress it like a smooth brained ape lol

Mainly I am happy with myself for being to get this product installed on my recoil spring. I watched the video a couple of times and tried to duplicate what I saw there. And then I gave up worrying about it and just did it. Once I got the split end of the wire inside the spring to spread open, and the little black plastic piece could be removed, I knew I was home free. I dropped in the new locking pin and rotated the spread wire so it closed. Job done! After that I had zero trouble getting the pin aligned in my new double finger charging handle. The only thing I discovered is that without M*Carbo's "cherry lifesaver", or recoil buffer, the butt end of my spring did not want to center on the piece that goes back in the end of the tube. An added benefit of the recoil buffer is to center that spring on the main buffer at the end of the tube. So I'm ordering again from M*Carbo to get a much-needed part.

This may be an excellent upgrade BUT after a few attempts, I have not been able to install the product.
