Question On Springfield M2 Sight Aperture
What's the correct aperture/sight disc diameter for the Lyman 48C supplied on the Springfield M2 .22LR training rifles? My M2 came to me with a 1/2" screw-in aperture but I'm not sure it's the correct diameter aperture as supplied new by Springfield. TIA for your help.
I just measured a couple of mine and they were both 11/16th's.
Thanks, Herschel!
Reading up on the Lyman 48 sight in Old Gunsights - A Collector's Guide, 1850-1965 by Nick Stroebel I found the following reference to the diameter of the sight disc, "Any eyepiece from 0.3125 to 1.00 inch would be supplied by request, but the standard disc supplied with most [48] sights was 0.6875-inch in diameter." 11/16th's decimal equivalent is 0.6875-inch
Anyone happen to know, other than a gun show, where I might acquire a Lyman 0.6875-inch sight disc?

You might try Aperturesnmore: http://www.aperturesnmore.com/produc...&categoryId=10
They list a 1/2 and 5/8" , but they make them so I don't believe it would be any problem for them to make a 11/16". Their prices and customer service are excellent.
The sight discs are, or at least recently were, available from Lyman. I suggest you give them a call. They show up fairly often on the gunbroker and ebay auctions. I would do a search there for Lyman Sight. Some sellers may not know that it is a Lyman item. A search for simply "sight disc" or "sight aperture" might yield results.

I hunt with my M1922, and find the aperture to be a handicap. So I took it off, took off the buttplate and put it in the profiling lathe hole. If you have an M1922 with a missing aperture, look under the buttplate.
5/8 = 10/16. Isn't that close enough? Special order will cost more, not worth 1/16"!Originally Posted by Dollar Bill
