Grey Birch R700 owners - what’s the lightest it can go?

[LRshooter6mm]

I’m tossing around the idea of a hunting/possible NRL hunter rig in a Grey Birch chassis. If my math is correct, using their la grip and 5” forend I can get the weight to about 1.8lb. Can anybody validate this?

Their LA grip says it’s 23 grams (.811 oz) which seems ridiculous light to me..

Grip is 56g (2oz) with screw
Chassis with grip and no forend is 952g (2lb 1.5oz)
16" forend is 282g (9.9oz)

You aren't seeing under 2lbs
