Question 1: The rifle style rear sights made by XS and Trijicon for the 870 use a 2 groove sliding base, but my old brushmaster has a dovetail slider. Does anyone currently either make the 2 groove base or sights that will fit my dovetail?
Question 2: My barrel takes a surprising amount of effort to remove, but it seems like most 870 barrels just slide off with no effort. My barrel ring seems to sits at an angle to the mag tube (I loosened the mag tube cap in photo 2 to show the angle) Should I be concerned? When disassembling I make sure the bolt is retracted and the magazine cap are removed, so I highly doubt it's user error.
