Bipod is a standard Harris-style picatinny/1913. The scope... Well, unless someone posts a good-quality screenshot showing some sort of logo or trademark I dont think we will ever know. IMO it looks like a Vortex Diamondback 3.5-10x50, with an aftermarket oversized zoom adjustment ring. These are sometimes used instead of throw levers as theyre less likely to get caught on things. Its a $300-$400 scope here in the US. Hes got some very low profile scope rings, but as said above youll probably need to go at least mid-height to have it be useable.
I've got one of these sat in front of me right now (I used to have it on my SRS)... It looks very similar to the one in the pic, but I'm not 100%.
The scope mount looks interesting as it looks like it can be elevated. @Jay851 I can recommend the SRS one piece scope rings as a good partner to the Diamondback, if that's the way you decide to go.
