Magazine cap detent

[Milwroad]

Several gun parts stores show a picture of a stemmed detent for the 870 magazine cap. Others show just a round ball bearing like detent. Which is correct for an older 870? Did newer models use the stemmed detent and earlier models just the ball bearing? Help appreciated. Thx

I've had no call to remove a mag cap detent on a newer 870 but, if a ball is used, I would bet that it's on newer model.
I have had several older 870's to reblue and all have had the pin type, staked in.
It might also be that whoever put the schematic together was lazy and grabbed a block of a ball to insert for a picture.

Edit - I just hopped over to the Numrich site and they show a ball in the schematic but if you click on the part #40, the detail part pic is of the pin type.

Remington went away from the ball-detent as it was more difficult to machine then the in-tube nylon ratchet end. You're kinda stuck with whichever version you have.
