Hey all, it's been a while since I posted here so I figured it was time for an update.
I'm in the process of putting a Williams F.P. receiver sight on my 464 SPX. I had been looking at them for a while and then I saw one on eBay, new/old stock, I got it for $17.50, a real bargain. At first I was going to take it to a gun smith but looking at it, the installation looked so simple, so I decided to do it myself. I used the base as the template for center-punching the holes on the side of the receiver. My son has a small bench drill press and he helped me keep it lined up as I ran the drill into it. The holes are a #31, and I went real carefully, measuring the hole depth with a vernier caliper so I didn't go through into the bolt channel (I really don't think it would matter if you did). Williams supplys the mounting screws, 2 x 6-48 machine screws about 5/16" long.
I mounted it so the horizontal slide is directly over the rear scope mount, so I can't have a scope mounted at the same time. I could have moved the sight rearward about 3/4" and it would clear the scope mount, but then it would interfere with disassembly, I wouldn't be able to get the 'Locking Bolt' out without first removing the receiver sight. I decided I wasn't going to use a scope (not for a while anyway) and I'd like to be able to disassemble it completely so...
I was also assuming I had to change the front sight, but that is not the case. The front sight is high enough and the receiver sight sits low enough so no change is needed.
I'm not quite done, I'm waiting on a 6-48 tap to arrive, but before the week's out it should be done.
I've posted some pics of it so far:
And here's the final installation, I ended up drilling 3 holes in the receiver I can use either the front 2 holes or the back 2. If I use the back 2 then a short scope base (very short) can still be installed on the receiver. With the look-through scope rings, both the scope and the Williams receiver sight will be usable. The receiver sight is aligned with the original iron sights so there's no need to remove it, it may even help the sight picture...
