A remix of a remix

This is made to fit mil spec buffer tubes but the original 5/16 bolt is just too large and loose for my needs, So I added a insert to make the screw size smaller to M6 which is better fitting for the tube and double the length of threads for strength.

You will either need to tap the hole for M6 or use a Heat Set insert for it, I sized the hole to allow either to be done easily for your choice.

I also made a relief to allow for a knob like this one https://amzn.to/3hmqPLI M6 x 35MM to be used.

I found M6 x 35mm to be the ideal bolt size for my needs.

As always this design is for show purposes only.
