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.

Once again you produce exactly what I need, thanks again Geordie.

My pleasure

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.
