Neat to see. My issue is the extra steps in casting in the voids for the mag well and trigger cut, along the specific shape seem like a partial waste of time. If one has access to machinery, it seems to me to be a better use of time to simply cast a large block of AL and take the extra machine time to mill out the outer shape and inner cuts. I mean, its cool for someone to show off their sand molding abilities, but if you have access to the machinery that he has, why not just cast a block and machine the whole enchilada.
