The 1895 Guide Gun is simply a variation of the 336, and the XS works just fine.
As with every accessory, the user needs to be aware of a few things, though.
Although rifle equipped with a ghost ring peep is just as accurate as the same one equipped with a smaller ID peep aperture, it is many times faster for game shooting.
The trouble is, that many ghost ring shooters try for tight paper target groups - for which a more constricted peep aperture is better. It's a better idea, to use the right tool for each job.
The XS ghost ring peep is available with the sighting stem threaded for an aperture, so an educated user may have their cake, and eat it too.
As with all top-mount peeps, a taller front sight blade is going to be needed in order to zero the rifle - or else it will shoot too high with the rear sight all the way down.
The best route for the average guy is to buy a peep set that includes the correct front sight - also available from XS, as well as Williams (w/FireSight), etc.
Don't forget to order a rear sight slot filler blank as well, and remove the rear barrel sight to clean/speed up the sight picture.
