Not .156 as advertised.

by Juan Diaz, Verified Owner from FL, United States Written on May 14, 2019
These are .1555. I have used them before and they always measured .156 as advertised. Measured against JP pins on had that did measure .156. Emailed JP, no answer. Called, got voice mail... no call back. Glad I didn't buy something more expensive from them. BTW, I have four of their triggers, never had an issue before
Pros:
  • None if you are not looking for .156 pins.
Cons:
  • Not sized as advertised.
Best Used for:
  • Standard build not looking for the difference in feel that these pins provide in .156.
Would recommend: No

Pros:

Cons:
  • None
Best Used for:
  • Replacing factory trigger pins or new builds
