Re: Trapdoor Carbine Front Sight

Posted by Bill M. on Sunday, 15 August 2010, at 11:58 a.m., in response to Trapdoor Carbine Front Sight, posted by Ken Klaumann on Sunday, 15 August 2010, at 10:51 a.m.

The Poyer/Riesch book gives this dimension as .815 inch. A few years ago, I was told that this measurement was wrong. However, I noticed that they did not change or correct it between the third and the more recent fourth editions of their book, so I am assuming they thought it was right. When I built my first carbine (like you, I recontoured an earlier cut-off rifle barrel), I brazed the front sight stud on at this distance. Comparing it to photos of originals, it looks correct-- and can't be far off. I feel certain that 1 1/4 inches is not right. Hopefully, someone who knows more on this can chime in.

As to measurements of the Carbine sight stud, the same Poyer/Riesch book says it is .415 inches long. There are also dimensions given for the front sight blade, but they vary considerably by model and year-- in other words, it depends on what year and period carbine you are planning to replicate. Hope this helps. Bill M.
