So my go to shop generally has huge discounts this time of year to clear out inventory before tax time. I stopped in a few minutes after they finished changing the tags.
They had a Mossberg 500 with a ported and choked barrel and a God awful paint scheme. I picked it up along with a pistol grip for $150.
After swapping out the stock and taking a hacksaw to the barrel I attached a mounting solution for a strap on the grip (fancy way of saying I ran a zip tie through the sling loop and taped it down) and hit it with a coat of paint.
I still need to do some file work on the barrel and rib but for 150 bucks and a solid hour worth of work I am pretty pleased.
