Though Geissele seems to dominate the topic of aftermarket AR triggers, I’ve long been a fan of Timney Triggers when it comes to other applications, so I figured I’d give them a try when it came time to upgrade the trigger on the AR9 project gun.

So, after watching for deals for a bit, I ended up snagging one for a decent price from grabagun.

I went with the flat bow rather than curved, but even their curved one is quite a bit straighter than many AR triggers.  This is mostly personal preference.

So, the neat there here is – compared to many other AR triggers available – these units are pre-assembled in an aluminum housing that just drops right in place.  Not only does it make them a snap to install, but you can swap them out just as easily.

How to Install:

1. 1. 1. Typical safety disclaimer:
         Make sure the firearm is unloaded, have no ammunition in your work area, wear protection, look both ways, etc.
      2. Remove the upper receiver.
         
      3. Remove the Grip, being careful not to lose the Safety Detent & Spring.
         
      4. Carefully remove the Safety.
         
      5. Remove the remaining pins holding the trigger assembly in place.  You’ll need these when installing the new trigger.

         

      6. Remove the trigger assembly, and toss into the parts bin / trash.   Seriously though – you probably wont want them again after shooting with a proper aftermarket trigger.
         
      7. Enjoy the satisfying *thunk* from dropping your Timney Targa trigger into place.
      8. Line up and replace the pins.  Note that there won’t be much tension on these yet to hold them in.  We’re about to remedy that.
         
      9. Using the provided Allen Wrench, tighten the set screws in the bottom of the trigger module housing.  There’s one on each side.
         
      10. Replace the Safety.
          
      11. Replace the Grip, being sure that the Safety Detent and Spring make it back in there.
          
      12. Function test the trigger and safety, then do a standard AR function test once you replace the upper.
          

    

Listen to that gorgeous reset and hammer fall.

I can’t wait to try out the Timney trigger I’ve selected for another project, currently being worked on by our other writer.
