Ive done some extensive gun smithing to my guns...just ask around....The plain B' model probably wont be a problem for those with a high mechanical inclination...but the D" models...PCR/PO1 included are much more complicated to takedown and put back togethor....
I can recommend a great smith to you in UT....he did my PCR and installed my PO1 trigger. VERY VERY reasonable.....hes in UT. Let me know if you want his name.......
ID highly recommend not only using a reputable smith to do this but one with D" model experience.
Shoot well....BTW..the difference in the triggers is amazing.
