Jim, Well said.
As you know, I have put together an A4 using one of the cmp receivers. It was a long process but I stayed within my budget. I did make some compromises, but I did that from the start so it was part of the overall plan. The compromises were in the optics. I want to shoot mine, not worry about destroying a expensive scope that could let loose at anytime. It's certainly not an cheap and easy route to go, but in the end I know what it is and will never be "pissed off".
As the late Turner Kirkland was fond of saying, "If you want good oats, you have to pay the price. If you'll take oats that have already been through the horse, those come cheaper."
