I have a LH PFS for sale. I bought it to build a Blaser, and it ended up being to much. My loss is your gain. I have everything in the pics, plus an extra comb. $900 Shipped. OBO
You'd have to buy a RH comb and make some minor changes on the unit to convert it to RH which is about a 5 minute job.
You also need to move the top rod from the LH side to the RH side. The front part is easy (loosen set screw, spin out rod, spin rod in other hole, move and tighten set screw), the back part may not be so easy since the cap screw holding it in place at the butt end is red loctited in place. You may be better off sending it to Target Shotguns to have it switched vs trying to do it yourself.
