Order today! Note: This drum may not fit some bullpup 12 gauge shotguns due to the angle of the pistol grip preventing access to the mag well for drums. Bullpups vary with some readily accepting the drums and others being awkward in regards to insertion and extraction. Use caution when ordering for use in an AR-12 bullpup.
