must have in your tool box

by Sdt, Verified Owner from MS, United States Written on July 27, 2024

Best Used for:
  • Action work and fitting.
Would recommend: Yes

Strike Industries AR Trigger Hammer Jig

by albrigrp, from MD, United States Written on July 3, 2019
If you want to see what a trigger group would do in your mill spec A.R. this is the jig to get it done. You can see pre-Travel and Post Travel along with the disconnect and lock up engagement. If you like to tinker with your own trigger group do you need this jig. Install your own A.R. pistol grip to match your custom build.
Pros:
  • easy to use
Cons:
  • A little pricey
Best Used for:
  • Custom trigger jobs
Would recommend: Yes

Great for troubleshooting trigger functionality for 80% lowers

by locomoco, Verified Owner from CO, United States Written on August 14, 2018
I installed a binary trigger into an 80% lower and it that wasn't passing the function test. I used this jig to verify functionality of my binary trigger and concluded that my receiver pin holes were not in alignment, thus failing the function test.

Useful but over engineered

by Scott KD, from SC, United States Written on May 27, 2018
There are too many cut outs on the sides. The oversized cut outs actually make installing a trigger or hammer harder because the springs bind in the cut out holes. Despite these limitations. It’s better than other products I have purchased for this purpose .

AR trigger jig

by Avid shootee, from TX, United States Written on May 3, 2018

  • Easy use
Cons:
  • None

  • Trigger jobs
