I'm also tempted by the WARG (and also the BiFrost, which is a couple of hundred cheaper at Eurooptic...it's the same stock up to the fore-end). I'm building a rifle on a Curtis Custom Vector and will be using it as a crossover hunting rifle with a 16-18" 308 barrel (Light, pointable and handy in box blinds and trees) and target rifle with a 6.5CM barrel.
One of my biggest concerns is that they are BDL vs DBM. I wonder how big an issue would it be to have it inletted for KMW Bottom Metal?
I've fondled a Berserk and the ergos feel amazing (assuming you rarely if ever want to shoot lefty).
