Kel-tec sub 2000 hammer locks but not fully back

Hi Guys, I bought a new sub-2000 a couple months ago and have not fired it yet (plan to on Saturday). The first time I checked out the gun I managed to pull the trigger (with the bolt out) and release the hammer. I immediately got on youtube and saw how to push the hammer back with a dowel. When I pushed my hammer back it locked but not down far enough to let the bolt slide by. If I push the hammer down and push the bolt past everything seems to function properly. Charging handle, safety, trigger etc all function properly. While waiting for the range to reopen I installed several M Carbo items including a trigger kit. After assembly I had the same problem. I disassembled the rifle and reassembled it again but still the hammer locked but not fully down. Again I used a dowel to press the hammer down a little further and slid the hammer home. Again, everything seems to function properly. HAS ANYONE ELSE HAD THIS PROBLEM? Is it even a problem?? Thanks in advance for any assistance.

Yes and No.

In that order even.

The hammer is probably fully down but some Subs (mine included) require more force than others to get the bolt to slide back over the hammer. You will find several threads discussing this. I personally use gravity by holding the firearm muzzle down, inserting the bolt part way and properly aligned and then dropping it. The weight of the falling bolt carries it over the hammer.

Thanks guys.
All I needed was a pat on the head.
Feeling warm and fuzzy, think I’ll take a nap.

This is common. I just push the bolt handle hard and it slides over the hammer. Can’t hurt it - it slams a helluva lot harder when you fire it.

I always put the safety on before I take out the bolt because it’s such a pita. :slight_smile:

I usually put my pinky finger in there and push the hammer down a bit until the bolt slides by it. Totally normal. Many threads and questions about this on this site. Lol

Hi. New to forum. Received new Sub-2000 gen 2, not fired, installed full MCarbo package. Having same issue as mentioned in this thread, except after pushing hammer down a bit to get bolt forward, the bolt will will not lock back no matter how hard I pull. Goes back almost all the way but a little short of where you would lock back. Have assembled and reassembled multiple times to try and figure out but at a loss.

What am I missing? Any one else have this issue? Any suggestions?

Thank you! Appreciate the experience and knowledge of this forum.

Never had this occur to me so I cannot be of much assistance.

In my experience, i didnt have the spring fully seated into either of these two places.
1.)the recess in the rear stock plastic pin/spring retainer.
2.) The new tool-less locking pin into the charging handle hole.

I ended up 1/4" short of getting the charging handle into the locking slot.
If you can wiggle the charging handle and see any vertical movement, the front of the spring is not fully seated.

Thank you, that makes sense. I have the recoilless charging handle and the tool-less locking pin. Am I supposed to replace the cap end of the spring with the tool-less locking pin? I have not done that. I have put some synthetic grease on end of spring cap to keep the locking pin attached while inserting into charging handle. The mcarbo bundle install video has a different locking pin than the one I received and that is how they showed to install it.

Just noticed on MCarbo site an install video for the tool-less locking pin! Boy what a bone head!

Thanks Stircrayzy for leading me in the right direction! Man been messing with this thing for many hours. Should have signed up for this forum at the beginning!

Take Care.

You got it ! Happy to help, and feel free to jump into this month’s match when you go to the range and try her out.

Just watched the install video. Yes, this does not look fun at all. Wish they would have included a new capture spring with this locking pin already installed as part of bundle. Thanks for referencing the other thread on this topic. Will be getting to this in the next day or two so hopefully I will not lose any body parts or blood.

It can be installed in a few minutes.If you have someone pull down on it, it takes 30 seconds. It’ll be much easier than you imagine.
Or use the twist method with same quick result
