neodymium magnet apertures for rear iron sights

[rfd]

Old eyes like mine can all too easily have issues with iron "U" and buckhorn style rear barrel sights. Been thinking on this for awhile and come up with an easy, fast and non-invasive solution that has been working really well for me. I use powerful neodymium (rare earth) ring magnets magnetically stuck to rear iron sights. Once stuck they won't budge unless some goodly force is applied. They can be moved up/down and left/right as the rear sight allows. Just look through the magnet "peep" and it'll automatically center the tip of yer fron sight perfectly, every time. These little ring magnets are less than a buck each and I get mine in different outside and inside diameters from kjmagnetics online.

Neat trick! Thanks.

That's pretty slick. I've already lost apertures for my Skinner sights in the field. I have a feeling I would be able to lose these as well :laugh:

If you have not seen the strength of there rare earth magnets, they are not easily getting knocked off.

I like this,gotta give those a try,thanks.

And you'd think that an aperture that's screwed in multiple threads and set w/ loctite wouldn't back out. I am aware of their strength. But you underestimate my habit of losing things in the field ;)

OK, nothing and nobody is perfect (I was tempted to say fool proof but I am sure you are not fool :-).)

Got one under the rear sight on the .69 rifle. Won't move for nothing.

these are mostly n42 neo's, with magnetic attraction strengths of between 2# for the super tiny ones and 5# for the larger ones. for added holding magnetism, increase the ring's thickness for double the magnetic gauss rate strength.

the one shown below is the stronger n52 neo and is sized at 1/2" od x 1/8" thick x 1/8" tapered hole and rated at nearly 8# holding strength. real tough to move. in any event, it's a good way to check out a rear aperture without messing up the sight itself. i will say that once i started using these dang things, it's been hard to go back to a U or buckhorn, so be warned! :)

These would be a very good solution to installing a smaller aperture on a sight with a fairly large flat surface. I have in mind the No.4 Enfield with the flip-up aperture sight. I stuck a carburetor inlet seat in the larger hole on the back of a sight to get a smaller aperture, but this looks to be a more readily adjustable and removable solution.
