Quoted:
Was curious if anyone knew how many pounds a basic trigger from a PSA LPK is.
Never measured on but I would be shocked if it were less than minimum mil-spec (5.5 lbs).

I put one in my recent build and it does not seem to be any
heavier than the LWRC enhanced trigger group I have in my LWRC M6A2. I
dry fired them back to back a few times and honestly can't tell a
difference. Both are smooth according to my feel and not very hard to
pull back.
The LWRC makes no guarantees as to its pull weight. It just says it's smooth so it's pull weight won't be less than min mil-spec requirements. Saying a trigger "is not very hard to pull back" is completely subjective based upon what you're used to. If you're happy with it, that's all that matters.
Quoted:
Are expensive triggers over rated , or is the LWRC one I have
just not as good as the higher end triggers?
If by "expensive" triggers you're referring to ones that cost around $200 and up, IMHO they are not overrated. Triggers like the Geissele SSA-e are guaranteed to be super smooth and break at a specific weight (e.g. 3.5 lbs) unless they're pull weight is adjustable.
I've had 8 different stock triggers (right from LPKs or with the complete rifle) from DD, PSA, Bushmaster, DPMS and Colt. They all varied slightly in terms of pull weight and feel (gritty vs. smooth) but I just finished replacing all of them with with Geisseles (SSA and SSA-E) and it was worth every penny. The pull weights between them (same triggers) are consistent and smooth.
