Serial number look good and I am convinced this is a real Geissele (so I am not calling the authenticity of the product into question).
Anyways, I installed it in a brand new Noveske Gen 2 lower and immediately noticed that something was different when cocking the hammer using my thumb. There is a great deal of metal on metal rub compared to my other 6 geissele triggers.
Relevant installation notes.
- Cleaned and degreased SD3G upon delivery
- Verified correct Geissele pins (dimples)
- Cleaned inside of brand new Noveske Gen 2 lower (non-chainsaw)
- Mounted disconnector inside SD3G trigger and confirmed that disconnector spring was installed with fat side seated in trigger
- Applied Shell 33MS to all wear surfaces on trigger/disconnector
- Installed SD3G tigger portion using a couple drops of oil on the trigger pin
- Visually inspected for correct installation of trigger spring
- Applied Shell 33MS to all wear surfaces on hammer
- Installed hammer correctly using a couple of drops of oil on the hammer pin
- Visually inspected for correct hammer spring orientation
- Visually inspected that hammer spring leg was laying across groove on trigger pin
If you you have sound turn up on the video, you can easily hear the issue in question. Also, the hammer travels back a shorter distance on the newer SD3G before making any metal-to-metal contact.
New trigger - Noveske lower
Older trigger - AXTS lower
Sounds weird. Send it in with a note and let us look at it. On the note say Bill wants to look at it
So my question is... Is this normal? I don't remember any of my Geissele's ever feeling like this. Also, did production methods change fort these triggers? None of my other Geisseles have the circular forge marks.
Any info would be greatly appreciated. Thanks!
