K31 with new weaver scope mount (pic heavy)

Hello everyone, I've had my K31 for a long time but never posted it before. I recently decided to scope it and take full advantage of the potential accuracy. I found this mount locally although it was quite expensive. I don't know who makes it as it has no markings and came with no packaging but it's rock solid. It replaces the factory rear sight as I didn't want to permanently alter my trusty rifle. If anyone has seen these mounts before and is aware of how they hold up over time, please let me know! Along with it I got a Vortex Viper 6.5-20x44PA mil-dot, a set of Leupold rings and an extra magazine. I'll have to let you know how it shoots after the weather warms up a bit. Anyway, here it is!
