I dont know if this is the correct forum, but I assume someone knows the answer.
I want to exchange the front sight on my Ruger No 1, and I dont know the measurement of the slot. Is it a 3/32 or 5/64 or what? I would like the height to be approximately 8 mm high, which NECG would fit that description?
Thanks for answers.

They do not interchange but it is pretty common for people to mill their Rugers to accept NECG inserts. Cheap job; a lot of smiths already have the cutter. If not in your area, it is available from Brownell's.

Ok, thanks Tiggertate! So I have to either mill it to take other inserts, or buy Rugers stuff? Does Ruger have any good sights? I am not too impressed with the original, sad to say...

I haven't seen their current offerings but they used to have some variety in aftermarket inserts. Not as complete as NECG.

This is the NECG site I ordered for my No. 1 Tropical.

(Edit-For some reason I can only link the home page, go to "Front Sights" then to "Beads for Ruger Rifle", at the bottom of that page is the instruction to measure height. The site I ordered is the first one on the top. Click the "Purchase Button" and you can select the height.)

All that was required to install it was very slight shaping with a file (I mean very slight) and cutting about 1/8 off the front of the at the notch. Installation took 5 minutes.

I bought the 3/32 white bead along with the Masterpiece rear and love the sight picture.

Ok, thanks alot Mike and tiggertate! I think my problem is solved, thanks to you and AR.
