I have just purchased a lightly used .308 Troy PAR and will be watching this thread for ideas. It is currently in transit, so I have not even seen or handled one yet. The main modifications that interest me are:
* Trigger - I have a RRA 2 stage on my AR-15 that I reallly like and am used to, so would like to replicate it on the PAR
* Bipod - It seems that a bipod would be better than a bag or rest for a pump action - I'm curious what the mounting options are, since there does not appear to be much lower rail space forward of the pump mechanism.
* Stock - I really don't care for the Troy stock, I think the Magpul UBR would look great on this rifle but don't like the price. Maybe an STR
* Pistol Grip - The Magpul MIAD fits my hand very well, I have it on my AR-15 and SR-22, so this is probably the way I will go.
* Scope/Mount - I have a spare Sightron 4-12x that will get installed for now, not sure what optic to go with long term. I have had good luck with Burris PEPR mounts, so will probably stick with that or a similar mount.
Here is a "before" picture form the seller (scope and mount not included):
