MPR Trigger Adjustment

Mon Nov 09, 2015 8:35 pm

Hi, the trigger on my MPR is still set as it was from the factory and is a little heavier than I would like it to be, as I am using it for FT, could anyone give me any tips on which screws to adjust to lighten it a little without having to change or cut any springs.

As far as I know there's one screw by the trigger guard which is the weight of pull? And the two on the trigger are the 1st and second stage.

I like the feel of the stages as they are, I would just like the second stage lighter, so should I adjust the weight of pull screw or the second stage.

There is a fantastic guide on adjusting the s200 trigger by "timminder" I think,

Is there anything else on here for the s400/MPR?

Assuming that the MPR is the same/similar set up to the 4/500 series you might find the below link useful. It's the one we used to have in the tech library on the old site.

Can't recommend this guide enough, it's transformed my gun.

Much better follow through and no "pulled" shots anymore!

I highly recommend doing the trick with a small nail/panel pin to limit the travel .

Also, any newer type s400's or mpr's like mine will have a 3 sear set up , but the set up instructions will still work all the same.
