If you buy a quality BCG for the CL upper I’d assume they’ll all be soft shooting, and reliable. How much accuracy you need will probably be your determining factor.
The BCM will probably be the least accurate, but the lightest.
The Geissele will be excellent. Mine and a friends are both 2moa for 10 shots, fwiw.
If you get the CL be sure to buy a quality BCG for it.
