i bought this over the internet listed as a model 8 or 81 peep sight its a williams the box it came in says williams shotgun but the sight does not fit in the box quite right has anyone seen these for the 8s or 81s?

Yes, Pack is correct. The Williams 5D-SSM is correct for your 8/81 rifle. I got one some time back for my 81.
