I was assembling some lowers today and was thinking about how I was going to make my adjustable stocks "MA legal". I am aware of the methods out there to do this, but was thinking outside of the box. Looking for input before I make a bunch of these:
Picture A lego type block that will have two bosses that will fit into two of the counterbores and the slot of the buffer tube. In between them there will be a hole the same size of the C'bores in the buffer tube (my drawing shows a C'bore, but a hole will be easier from a manufacturing standpoint). This will allow the pin that normally locks the stock into place to be locked in, but it will lock into the new block. The block will sit flush with the surface that the pencil is pointing at in picture 2. This will prevent the stock to be adjusted "on the fly", but will still allow it to be disassembled by pulling the pin as you did when installing the stock onto the buffer tube.
So far, the only downsides to this I can think of is that you will lose about a 1/2" of length of adjustment on both ends of the buffer tube.
Any input is appreciated.
