M-300 Claymore Heavy Shotgun

A very rare krogan shotgun. Deals high damage at short range; less effective at long range. Effective against armor, shields and biotic barriers. It is of human design but is only used by krogan, due to the fact that the kickback from a single shot is enough to break a human's arm. Can be acquired and used by Shepard if you choose it as advanced training when the option arises. It has the lowest clip size of any shotgun, firing only a single shot before the thermal clip has to be ejected. It is protected by Fabrication Rights Management (FRM) technology, this weapon is nearly impossible to reproduce and is prohibitively expensive.
