Psycannon

The psycannon is a weapon created specifically to combat daemons. It is a more powerful version of the bolter, utilizing high-caliber psychically-charged ritually-inscribed silver-tipped psycannon bolts. The psychic charge and ritual inscription on every bolt allows it to pass through any defensive shielding, whether it is created by psychic energies or technology. The weapon has a suspensor to offset the weight and allows it to be fired on the move although at a cost of reduced effective range.

The Psycannon is a weapon exclusively used by the Ordo Malleus and its Ordo Militant, the Grey Knights Chapter of Space Marines. There are a few notable exceptions, such as Gideon Ravenor of the Ordo Xenos, whose armored chair was fitted with a pair of such weapons. The Psycannon is generally wielded with both hands by the normal power-armored Grey Knights and most other operators, although members of the Terminator squads mount the psycannons on their arm instead. The method of feeding ammunition is similar to that of a heavy bolter, being an ammunition belt running from the ammunition store located within their backpack.

High-ranking members of the Ordo Malleus may use bolt guns which fire downsized version of the psycannon ammuntions. These are less effective than the Psycannon but more powerful than the same sized bolt weapons.
