Very soon I will drill my very first front sight base to my spare 6.8 barrel.
Going to make a GUU-5P phantom. Pseudo retro gun. Slick side upper, round handguards, fiberlite stock, A1 grip with a 6.8 mid-length barrel.
Should be spiffy.
The full fence lower on my M16 clone is moving to this project.
The M16 has all early features except for the lower so getting a partial fence is appropriate.
