  • someone tell me does it matter the direction of the trigger or hammer pins

  • You make it seem so simple, but I know if I try it, I'll screw everything up. LOL.

  • great video very well explained Thanks for posting

  • Does the hammer spring sit on the trigger spring or the trigger pin?

    Anyone help me out with this question?

  • don't forget your disconnect spring!!!!! as i did

  • Thanks for the video.  Fixed my function check failure problem. Flared disco spring goes down. I had it up. I appreciate the info.

    Best,

    JBR

  • Good Series man, Appreciate you putting it on youtube and investing the time to do so. I like Gen 2 .154 myself. But that's just me.

  • What size KNS pins are they .170 or .154? What size KNS pins would I need for a typical spikes lower?

  • Get a bigger hammer twitchy fingers shouldn't be working on any thing mechanical or it may be he is just nervously

  • @magurgle What do you have against KNS pins? I like my KNS pins. I installed a set on my new rifle and it functions really well with these KNS pins. The pins don't walk thanks to the KNS design and they even prevent a bit of "wobble". My trigger actually feels noticeably different, thanx to KNS and their pins. I will say that I called KNS about their pins and they had great customer support. Now all my rifels use KNS non-rotational pins.

    This is a non-compensated endorsement by CTKIX.
