CZ 527 trigger help

I just recently acquired a 527 Varmint MTR in .223. This model does not have a CZ set trigger(wish it did). It has an adjustable down to about 2.5# Not low enough for me.However It is crisp, and it does pull consistent 2.5 on the scale. Do any of you know of aftermarket support for this trigger? Any pointers on manipulating springs? I cant seem to find anything .

Ok

Try Yo Dave spring to get a different one for the trigger or rifle basic has a replacement I believe.

That's as light as you can go without a spring change. The clean break and over travel on the cz is very good though. I have 3, 2 with set triggers and one without, i shot all very good.
