SG22 Upper - reinforced

When slicing the stock upper I found that the walls around the charging handle recess were only 2 thick, reinforced that section for improved rigidity.

Print orientation threads up or down, .2layer height worked for me, be sure to check your horizontal expansion so the barrel nut attaches properly.

v2 has taller reinforcement around the charging handle slot
