Since interest has been expressed in the components of this BPS Combo, I've computed different costs depending on what you might select. None the less, the "slug barrel" will need to go before the gun.
BPS w/ tubes, wrench and gun chaps $475 plus shipping & insurance to your FFL from non-FFL
Slug Barrel Option #1 - Smooth bore (Fixed IC) barrel with cantilever mount, scope & rings $255 plus shipping & insurance directly to you
Slug Barrel Option #2 - Smooth bore (Fixed IC) barrel with cantilever mount (No scope or rings) $195 plus shipping & insurance directly to you
