Best stock for mossberg 590 - Magpul Industries SGA Shotgun Stock for Mossberg 500/590/590A1

This is the most comfortable stock due to the grip angle is good and easy reaching on the safety on the top of the receiver for a Mossberg 590. The adjustable pull length is also very customizable for the best fitting. Plenty sling mount position including traditional and QD holes. The screw is a little hard to access to and that cap for the screw is kind of flimsy. But I heard if yours is broken, Magpul will send you one for free anyways.

To access the trigger assembly, you would have to remove the stock. So this increase the effort of removing bolt for cleaning. But it is a pump action shotgun, so it is not like it got dirty all the time.
