Step 3Removing air restrictor and sanding
iImage Information

the air restrictor should've came out when you sawed off the barrel (its technically not an air restrictor but im just gonna call it that), but if it didnt you can either break it off or cut it off with a knife or something (be careful not to touch the black rubber inside the gun) and then you can sand where the old barrel was so that it is flat. (the picture is of how the gun should look now, and thanx again to nerfhaven.com and gengar003 for the picture)
