    There are other places to cut weight instead of the receivers.

    People have been making/building sub-6lb AR's with regular milspec lowers. Cutting or shaving the lower for weight reduction is non-sense, when you can reduce weight of the rifle in other places (barrel, stock, etc).

    If its only for cosmetic reasons (for a non-hard use rifle), then its fine. Otherwise, I think its not smart.

    You can get a bunch of weight out of an upper and lower without affecting function, or stabbing holes in it.... It takes some time to do it however.

    Of course, that is already understood.

    You didn't specify how this weight is reduced though. Do you mean using different materials on the receiver (magnesium, polymer/plastic, etc) ?

    Weight is reduced by selective machining in the right places. 7075-T6 Aluminum.

    An un-noticeable contour change on a barrel will shed far more weight than poking holes in the lower. Selecting the correct parts to build a rifle will shed more weight than poking holes in a lower. The 'low hanging fruit' is not excess flab on a mil-spec lower.
