Benelli MP90s Adjustment screw

[Rudi]

Is there an off the shelf replacement for this screw 071p?
Mine came pretty beat up, probably due to an ill fitting screwdriver from the previous owner.

Even a hex key version is welcome.

On a side note, do folks use a custom rounded screw driver for this? I've seen others use a coin, or metal disk placed in a wooden handle.

Unfortunately, no. They use a fine thread, and the detents for the elevation require multiple little dimples on the underside of the head.

It's designed to use with a coin. A penny works & is soft and won't mar it.

Jim Henderson, who bought LGI's stock of parts when the owner died, probably has one. The question is whether he can find it...

I think it's standard M3, but yeah, very special shape. You'll need the authentic item.

One possibility might be to repair the top surface, with epoxy or some careful filing/machining. Probably not worth it.

Tip: if you remove it, be sure to tie the sight down with a ziptie because the tension spring might escape the pocket. If this happens, you may have to remove the sight pivot pins to get it all back together.

Thank you both as always
