Gunsmithing Need help with component weights

[Jig Stick]

I'm picking some components for a hunting rifle in 270 and I'm trying to keep the weight around 8.5 lbs max. Can someone please tell me how much the following weigh?

Jewell trigger with top safety

Talley light weight rings for a 1in tube

Recoil lug

And Remington style bdl bottom metal

Any help would be greatly appreciated
