M110 Accessory - What is it?

[Pugster]

I was watching some M110 / SR25 videos online and saw a wheel/drum accessory mounted near the rifle rear (See attached pictures).

Does anyone know what is the name of it?

I thank everyone for your help with this.

i'm curious, but it seems like an easy way of keeping a dope "card".

I cross-posted this on SnipersHide and it's a Badger Ordnance Angle Cosine Indicator.

It's nice to finally know what it is
