How to increase AR15 trigger pull?

[HeadDamage]

My AR15 is just above the legal weight limit for DCRA service rifle and I would like a little extra margin so would fitting a stronger hammer or trigger spring increase the pull? Any other way of doing it? Thanks.

oops... I misread... ignore my post.

Stronger trigger return spring.

You mean the little coil spring under the disconector?

No, the one other than the hammer spring. I do think a heavier disconnector spring would add some pull weight too.

Know anyone that sells a heavy trigger return spring in Canada?

Replace it with a Wolff unit.

Potentially (and I have never tried this) you could "re-bend" the spring to increase resistance.

I run KAC 2 stage triggers in mine - KOLDT has one if you want to see them -- it is supposedly a #4.5lb trigger but has held up to the DCRA/CFSAC trigger pull gauge - and yet feels like a 1lb trigger.
