Not sure if anyone is still interested, but the pattern was a bit too high and right for my taste with a bead, so I drilled and tapped the receiver and put a small rail and dot on it.

To be fair, this was 2 shots at 20 yards after it was zeroed while shooting remington express long range #6 shot just to make sure everything was holding.

It was.

And a single shot backed up to 30 yards. Should be very adequate for those squirrels way up in the tops of those old oaks now.
