Williams still list a side mounted peep sight that fits the BB375:

You can also fit a peep sight that fits a “regular” 94, just use a file to contour the sight base to fit around the rear receiver bulge. I’ve done that to a Lyman peep.

As mentioned you can fit a XS peep sight, but the receiver will need to be D&T-ed to accept the sight. You’ll also need a higher front sight.
