FP Target Knobs, aks Grub screws
These are nice, fit well and make adjusting sights much easier. Review must not be less than 150 characters so, it is 38 degrees outside with a chance of snow, probably will not go shooting today.
Exact fit to upgrade to Target Knobs
Installing these are as simple as backing out the small locking screws, then screwing the existing elevation screw in until it forces the screw out past the detent ball. To install, push the Target Knob into the screw hole until it seats the detent ball. Tighten up the locking screw to taste and that's it.

Looks Good, but needs trim
I had to cut 3/16" off mine for proper fit to FP-39 and it is 6-48 threads. I drilled and tapped an 1/8" mild steel bar, threaded the screw into the bar, clamped the bar in a vise and cut the screw with a worn fine tooth hacksaw, then dressed the threads and end of the screw with a fine file. Removing the screw from the bar helps to chase the threads. I finished the screw by chasing again with a 6-48 round die. The Williams sight is aluminum and the fine thread only allows for one mistake!
Not for ruger 77
The short windage screw is too short for the fp model sight designed for the ruger 77 rifles. I returned it for the long instead, great quality and easy installation , and great service from brownells. The short elevation screw is correct for this same sight though, maybe this can save somebody the extra shipping I paid for my mistake
Fits well, but long
This screw is for some reason about 1/8th inch too long (same for the one for my FP788-TK). Either hacksaw or grind off the extra length to match the stock gib lock screw and it fits perfect. If it wasn't for the slight annoyance with trimming it to length, I'd give it a 5.
