Reversible CF Tube Stock

This is an adaptation of other creator's braces and stocks.  The stock/buttpad is elongated but my modification was not significant enough to include here, so the original saurkraut files or stock files need to be downloaded from the original source.  What I am posting is the rear part of the hinge and a drilling jig.  The sauerkraut brace was a great design and I liked the later adaption for a cf tube.  However, what I made differently was that I tightened the fit of the cf tube into the hinge mount to minimize any wiggle.  Then I added a place for an m4 bolt to hold the cf tube in place without any epoxy.  What this allows is for the tube to be reversed or inverted in orientation.  For a launcher type purpose, it is more advantageous for the buttpad to be turned upwards, but for normal purposes, it can be turned downward as one normally would expect.  This way it can be utilized on anything with a pic rail and reversed or inverted when desired.  Also included is a drilling jig.  With the jig and a 4mm drill bit you can drill a hole at the perfect depth to be used with the cf tube mount for the m4 bolt.  Just insert the tube all the way into the jig and use the flex of the jig to hold the tube securely in place.  Use a 25mm OD 23mm ID tube and cut to the desired length.
