My old eyes can't see iron sights any more. so an optical sight was needed on my Webley Alecto.

The problem is that although the top rail of the pistol is Weaver size, there are no cross slots to accommodate the securing screws, so it doesn't sit flat.

Initially I made sure that there was enough thickness of material in the barrel housing and I filed a slot in the position I wanted. This cleared the screw, but didn't look very good. O.K, I am the only one who will ever see it, but I wanted it better.

I removed the barrel housing and then milled slots the same as on the underside of the pistol, 5 mm wide by 1.2 mm deep and with a pitch of 10 mm.

The barrel housing is a composite material that is self coloured all the way through, so there is no nasty stuff showing where it has been machined.

Re-fitted the barrel housing, fitted the red dot and then did a five shot string at 21 foot.

Quite happy with the results.......
