I've read several threads about Remington's extended mag tubes shooting loose on 870s. Does anybody install ball detents which would correct this effect? Thanks.
My Marine magnum HAS a ball detent that came with the weapon. It's on the barrel lug that fits over the mag tube. The SGT and Vang mag extensions I have both have been machine to take advantage of this detent and the tubes do NOT shoot loose.
You know, I never looked on the barrel band for the ball detent. My M1S90 has it on the mag extension, so I just assumed the 879 did as well. I'll check it out tonight. Thanks.
I believe Brownells lists a tool for installing these detents. Hard to believe anyone would stop installing such a small but potentially important device -- think of the cost of paying off someone who gets injured over a $0.17 part?
