Title: Air Arms ProSport trigger adjustment screws - What size Allen wrench?
Post by: PaulK62 on February 15, 2024, 06:37:07 PM
Apologies if this has been addressed before. I searched, but came up empty handed.

Can someone please tell me what size hex key fits the little Allen screws at the front of the trigger? There's some creep on the second stage I need to get rid of. Any tips on that as well would be greatly appreciated.

Thank you,
Paul

Hi there,

Thanks,

IIRC a 1mm allen

Screw closest to backside of blade In ( CW ) @ 1/10th turn at a time .. test & repeat as needed.

If wanting a Longer blade travel 1st to 2nd stage ?, leave front screw alone & back off ( CCW ) the rear most screw in small amounts, test & repeat as needed.

Thank you very much. I'll give it a try.

It will be metric.
Smaller than 3mm.

But..I have the TX200 (probably the same adjustments).
I have had it since 2013…60,000 shots.
Never touched the trigger adjustments.

That's outstanding. Unfortunately, I bought my ProSport used. I don't know if the previous owner monkeyed with it or not, but the trigger suffers from some pretty bad creep. I'm happy with the purchase overall, but the trigger is definitely disappointing. I was told tweaking the adjustment screws can fix it. I hope that's the case.
