I never thought changing the screw used to mount my pistol grip on my AR could make much of a difference to my trigger but apparently it can if it’s the Trigger Adjuster Screw. It lets you remove the pre-travel from your trigger with ease. This simple screw is actually 2 pieces – the main screw and a small set screw inside the center of it.
The way it works is simple: when the main screw attaches the grip, the set screw is extended against the base of your trigger, slightly shifting it’s angle to help remove creep. And it works. I have a Hipertouch 24E installed in my AR15 but it had just a bit too much pre-travel by default. By using this screw it’s 99% gone and the trigger is perfect. Even our Hipertouch 24, and a stock RRA trigger in AR10s benefited greatly from this little adjuster screw. There isn’t much else to say other than it works, and works well!
Installation is simple but requires an extended Allen Wrench, sold separately.
- Set AR to Safe (important!).
- Remove existing screw from your pistol grip.
- Remove set screw from the AR Trigger Adjuster screw, apply blue Locktite and reinsert the set screw.
- Extend the set screw until it stops (and no further!).
- Test trigger function and back it out using 1/8 turns until it functions correctly.
Tada! – you’ve just removed the excess pre-travel from your trigger!
Great little accessory to help you tweak that trigger. I’ll be picking up more for future builds.
