WK 180 MCR Trigger Hammer Anti-Walk Pins

Out of stock

These pins are for those of us who suffer from walking pin syndrome. That is your hammer/trigger pins move out of position when you are shooting because something somewhere is a bit loose. These pins have threaded holes in the ends where you will install a screw to make it impossible for the pins to walk through the receiver. Ideally for aftermarket cartridge triggers like trigger tech.

  • Direct drop-in replacement for your hammer/trigger pins
  • Installs in a few minutes
  • Tools included

 You get:

  • (2) .05 keys
  • (4) Micro washers
  • (2) Pins
  • (4) Screws

Compatible with:

  • All Wk180 and MCR lowers and trigger groups with the small (0.154") but longer trigger/hammer pins

Installation Difficulty: 

Tools required:  Included hex keys

Installation notes: Simply swap in theses new pins and install the screws so they can't walk out. one might consider a drop of threadlock juice like Loctite. You need to use both hex keys to prevent pin rotation while tightening.
