Ugh. Just spent hours working on my Sub2k to get the All-In-One Pro kit installed. What a miserable experience. I should have just sent it to MCARBO and had them do it.
Major points of frustration:
- The Sub2K was obviously not designed to be worked on/serviced. It’s a lousy design for serviceability.
- Exploring the innards of the Sub2K only reinforced my opinion of Kel-Tec that they make very cheap quality parts/firearms.
- Loosing that G-D sear spring TWICE! (never did find the MCARBO one, had to re-install the original)
- Loosing the G-D safety detent spring (never could find it)
- The MCARBO Armorer’s Tool was more hinderance than help getting the safety’s C-clips off. The end of the tool is the correct width, but the teeth of it flair outwards (not inwards as they should). The only grip I could get on the C-clip captured both ends of the clip and no amount of pushing/twisting/f-ing-with-it was going to push that C-clip off. The design of the tool was working against me and the clip. I ended up getting a pair of needle-nose vise-grips and pulling the ring off that way.
- The MCARBO trigger spring that I got was NOT bent to spec. It was the RARE exception of comparing the MCARBO parts to the Kel-Tec parts. Most of them it was obvious the MCARBO part was MUCH higher quality. But the spring I got was not bent properly. It’s hard to describe, but it wasn’t “square”. I had a very hard time getting it bent into the proper shape and had to assemble/disassemble the receiver halves several times to get it right. It was very annoying, and after loosing the G-D sear spring twice, I wasn’t in a cheerful mood.
- The Sub2k assembly dowel was another frustrating tool. It was just the right diameter to get jammed between the hammer and the walls of the buffer tube/receiver. I literally have wood shavings inside my Sub2K! What a pain in the ass just to get the hammer cocked!
- Lastly, while assembling the safety, the detent spring came out inside the receiver. I couldn’t get it out and ended up having to disassemble the receiver AGAIN, only to not find the detent sping inside the Sub2k either. I have no idea where it went. It’s probably partying with that damn sear spring somewhere.
So, I can’t even reassemble my Sub2k right now. No safety installed means you can’t install the bolt (which is probably a good thing for safety reasons, but it would be nice to put it back together as much as possible while I wait to get another detent spring).
Dammit. I wish I’d have just sent the damn thing to MCARBO and had them do the install. And this from a guy who has built from scratch multiple ARs. I’m not a bad DIY-er. I’m good with my hands and with tools. But this Sub2k has me really pissed off right now.
