The J19 electroscope was a type of macroscope used in the Sonn-Blas Corporation F-11D blaster rifle, a standard-issue weapon in the First Order. The macroscope provided eight-times magnification, low-light capabilities, and, for Snowtroopers, antifogging filaments. The J19 was adjustable and the F-11D blaster rifle was carried by First Order stormtroopers. The First Order Captain Phasma carried a modified F-11D blaster rifle, which also was equipped with a J19 electroscope.
