Im looking to get a new base for a rifle Im setting up and Im having a hard time figuring out what to go with. I have a new Remington 700 Police and it does not have a detachable magazine, just a hinged floorplate. Im looking at a 1 piece picatinny rail but im concerned that it will be hard to feed rounds into the internal mag from the top of the receiver. Should I go with a 2 piece base or stick with the one piece. Thanks
