Re: POF 308 PRS compatibilty
On a POF P-308, you can NOT use an AR-15 PRS because the charging handle will not operate properly IF the cheekpiece is raised at all. Your CH will contact the leading edge of the cheekpiece and not pull back far enough to cycle the action/chamber a round. You CAN modify an AR-15 PRS to work on an AR-10 type action, but it requires you to hack up the cheekpiece to relieve it for the CH to operate properly.
If, however, you just want the ergos/features of the PRS and do NOT need to raise the cheekpiece any for a proper cheek weld, then an AR-15 PRS will work on the P-308.
