mp5 style handguard not complete. UPDATED previous version didn't allow the bolt to move forward enough to go into battery without shortening the charging handle so i've updated the cavity, changed the spiral looking nipple to a cap that accepts a magnet, use 3mm diameter barstock to to secure the cap. m3 bolts will probably suffice in a pinch
