My rail button selection has dwindled over time, so I recently went on a search for replacements.
I saw an ad for Dog House Rocketry, visited the web site and based on what I saw pulled the trigger on an order. I purchased both 1010 and 1515 buttons in black and white, and I have to say that the quality is first-rate. Screws are included, but to me the best part is that the buttons are countersunk on one side. That means that the screws are flush with the button and do not stick up, thus eliminating any chance of the screw binding on the rail.
Bill shipped my order quickly and it was packaged well.
Give them a look...
I'm not a paid spokesman, just think that great products and service need to be acknowledged.
