Thread: Shout out for Howa

Can you explain the trigger mod - I bought a Howa Mini (6.5 Grendel) for my son. Great little rifle. The trigger has the white silicone on the adjustment screw from the factory. We haven't adjusted it just ? Cheers

All it does is adjust trigger to sear engagement.
Winding it out will lessen that engagement therfore allowing it to break with less travel.
Depending on the finish of the internals and trigger spring, it will determine how good you can get it without any other work.
If you still have the manual it should be in there somewhere.

@R93 - I don't believe that is correct. The white silicone covers a small screw and locknut that retains the actuator spring and enables it to be preloaded(this is close to minimum adjustment from factory in my experience).

The Howa HACT trigger modification that can be found on YouTube reduces the overly heavy trigger pull by reducing the preload on the stock actuator spring. By removing length from the spring preload is reduced on the actuator bar, lightening trigger pull.

Changing the sear engagement is a risky exercise for the inexperienced and certainly something that I would only get a trained gunsmith to do for me.

If you Google 'Howa HACT trigger diagram' there is a nice image that makes it easy to see.

I hope this helps! Cheers, Marc.

Agree with @Steelisreal about the HACT trigger on the new Howa's
This diagram might help explain the differences

You snip a coil and a bit off of a spring inside the trigger unit, to significantly lighten the trigger.
