Saddle mount for Remington 870 SP

[Ches.]

I currently have a vent ridge picatinny adapter and then picatinny rail mounted to that. The adapter makes it higher and is hard to get square with barrel. I was wondering how well some of the saddle mounts work. They look to be lower and I would think straight with barrel. Experiences? My receiver is not tapped.

I have a saddle mount on a youth 870 20 gauge slug gun and it has never lost zero. Sorry I don't remember the brand (I just checked no mfg stamp) but it mounts using both trigger group pin holes.

Thanks, I figured they would but was not sure. I am 71, and started looking at things differently. If I were 50 or 60 I would either buy a new gun or see what a gun smith would charge to dill and tap mount holes. That would be the best to get sight low, but that's not what I am going to do.
