Does anyone know the real differences between the KAC sandcutter carrier (around $200-$220 without a bolt) and the LMT enhanced BCG (around $270 with the LMT enhanced bolt)? The sandcutter is chrome, but aside from that I'm not sure if there is really any big difference that justifies the price other than the KAC name attached to it. Would love some additional info if anyone has experience with both.
