When zero-ing at the range I noticed the front sight post is canted to the right. It is also loose and can be easily moved right to left just using your finger. I tried elevation and windage adjustments but it stays loose. Do I need a new front post and spring? Thanks for any suggestions.
welcome! you came to the right place but got the wrong person to answer (me) - someone who knows will have a good answer for ya.
I suggest calling mCarbo support. My experience with them has been great.
From your question, I’m going to offer two solutions.
Performance Services offers this fix for An unpopular design from Kel Tec.
And Red Lion offers this folding sight which many of us used to replace Kel Tec’s factory sight.
First of wast itthe originali site or a MCarbo mod?
If it was original then contact KelTe.Is it was an MCarbo mod then contact them.
The front site should be tight or a sight movement. However the aignment when it closes and latches it may move to lock. A remedy would be areplaceet tachnical lock.Keep us posted
Thanks for the suggestions!
When I touch the front sight post the entire pivot block is moving quit a bit. There’s a small screw on the pivot block above the FSP but the manual says do not touch. I wonder if I can tighten down that screw?
I would gently tighten it, if helps torqur it. The warning was meant so people did not losen it by mistake. They were suppose to ckeck/set.if solves issue, then go back, remove , clean and reinstall using locktight with a torque wrench
I have 2 sub2k,s.first was sent to mcarbo for upgrades. 2nd was special addition already serialized and built for mcarbo. Used a bore lazer aligned and now both shoot groups of 3 sh[ts in less than 1 1/2 inch…at about 50 yrds.issue i have is charging. So bought new heavier brass bolts from keltec. Once new gun bench is finished being built i wi) polish them and the inside of tobe. A12ga mop fit perfectly.that should help tons.
Just got off the phone with MCARBO support…They said the exact same thing. You can tighten that little screw, but do not loosen it, unless you’re replacing the whole pivot block. I’m thinking that after several hundred rounds that screw can back out causing the pivot block to become loose. I’m going to tighten it down tonight and see if it works. I will let you all know how it goes. Thanks again for all the feedback.
Glad to hear. I would tighten, check/adjust alignment then tape and mark location. Once there then I would gently remove screw and add a dab of lock tight. If possible add without full removale. Tighten an torque in place. Remove tape , clean and enjoy shooting.
Always takes me a bit to remember, but …
Lifetime warranty on that Sub. You might call Kel Tec and see what they will do.
Blue. Because it tastes better than Red.
UPDATE: Tightening the small screw above the front sight post had NO effect on the canted post. You can still easily move it left to right with just your finger. The pivot block itself is still moving. I’ll contact support and see what they say.
The pivot block “pivots” by design. When assembled, a spring should return it to a repeatable position.
So, if you reach in and push it to the side, the spring should return it to proper position when you remove your finger. If it is not doing what I described, Kel Tec has a lifetime warranty that will get it fixed to operate as I describe.
So that pivot block is designed to move? OK…nobody told me that when I contacted MCARBO support. They told me to tighten the screw above the FSP (that didn’t help) So my problem is when I move the post it does snap back, but when it stops, the front sight post is still canted to the right. I wonder if I should just try to remove the entire FSP remove the detent spring and then re install it? Any thoughts?
So, I suspect your sight post is bent, or your pivot block is misdrilled.
I removed the front sight post and re-installed, it didn’t change anything. I’m going to order a new pivot block and see if that works.
