1. Unscrew the brass ocular lens housing from the tube thread. If it is tight borrow the wife’s dishwashing rubber gloves for some purchase on the tube and housing. If it is really, really tight, then you might have to warm the threaded joint area up a little with a hot air gun or hair dryer. With the Stepped tapered variant, if you are unlucky, sometime the brass collar of the brass ocular housing will unscrew from the brass ocular housing and stay on the tube threads. If this happens you will have to remove collar clean up threads and Loctite it back to the brass ocular housing.

If anyone has any questions, comments or additions for inclusion under the "Collectors Comments and Feedback" section of the MKL article, or ideas for future topics, that they please leave feedback for Valleysniper in the appropriate announcement thread.

Thanks to Valleysniper's excellent instructions I have managed to strip down my Periscopic Prism telescopic sight without any problems whatsoever. He is obviously an expert in this field. Valleysniper, your help is greatly appreciated! My next task will be to replace the missing graticule cross-wire and remove a small speck of dirt from one of the lenses.
