- The Remington M40A1 is a sniper rifle manufactured by Remington Arms Company for the US Military.
- However, in Negima, the weapon is just an airsoft replica of the actual gun, presumably manufactured by Sun Project, since it is the only airsoft gun manufacturer in Japan that produces a replica with a wooden stock. However, the manga version seems to be semi-automatic and does not need to use the bolt action. This was used in both chapter 49, 86 and 155, they fire 6mm BB bullets enchanted for exorcism. This was used also as a weapon for the biathlon club activities in the anime. Written as a footnote on the early character design profiles in the manga, Akamatsu originally planned for her to use a normal Remington 700 instead. The reason of changing to the military model M40A1 is unknown, although it is a known fact that a rifle with a detachable box magazine might be better in some cases.
