As a 18 year veteran Police Officer, I have found that being 5' 8" and a stocky 240 lbs it has always been difficult to carry my standard length Mossberg 590 A-1 long gun in the field dragging it in and out of the cruiser without the concerns of knocking the dam thing into door jambs or dragging it against the walls at the worst possible times.
However I have recently found several You-Tube videos pertaining to a very unique bullpup conversion kit manufactured in Kentucky, USA by Bullpup Unlimited, the videos demonstrate how to convert your existing Remington or Mossberg 12 Ga. factory length shotgun into a much shorter bullpup without reducing the overall barrel length.
With the addition of a AR style grip, selector safety, adjustable sling mounts, picatinny rails for optics and other accessories I knew this was a product worth looking into.
After I placed my order with Bud's.com they were super fast with my shipping email updates keeping me posted on delivery times and it arrived on time and in perfect condition.
If you are not the above average gunsmith, I would strongly advise you to read the simple step by step instruction manual and follow it to the letter depending on the weapon system you are using and of course always start with a clean well lit environment free of distractions for about 2 / 3 hours using a clean, oiled, function tested, completely empty weapon keeping your 12 Ga. ammo separated in another room before you begin to avoid any possibility of accidents.
Once your old shotgun is completely reborn into a 12 Ga. conversion bullpup you may just find yourself enjoying a whole new level of love for shooting 12 Ga loads. (even slugs)
I would highly recommend this Bullpup Unlimited conversion kit for your ultimate 12 Ga. home defense weapon that has virtually endless "practical / tactical" possibilities.
P.S. Looking forward to the Next Gen BU-II version for the Mossberg 590-M (Magazine fed)
