I have fitted PSS10 trigger sears to the standard trigger mech and run a 150 spring. Been like it for 3 years or more now, no wear etc. trigger pull.... hard?.... I used to have my standard trig set so if you hit it on the butt end reasonably hard it would fire, it did back fire on me once and just missed shooting myself in the head when I used the rifle as a walking stick up a steep bank : I now have it set so it releases after slightly less than 1/4" pull but hard to pull it is not.... but then I'm not exactly what you might call weak or feeble

IF you go 0-trig, try get the 90degree piston/sear model. Slightly better design.

Chaotic

Again, DO YOUR HOMEWORK! Zero triggers are only made in a '90' design' its also why they come with a piston as the sear end is different to the stock unit :

Could be any of 3 things

1/ You've not fitted the hop rubber correctly

2/ You've put to much PTFE tape round the hop to seal it, 2 maybe 3 layers is enough.

3/ The little black upside down 'U' shaped thing at the back of the hop unit, hasn't been put back correctly when you assembled the unit.
