I have a mesa tactical 8 shell sureshell and a blackhawk KNOX nrs stock for a mossberg 500/590. They are in mint condition and ive only fired the 500 with the items on it once. The NRS i will let go for $35 and the sureshell carrier i will let go for $60. No reasonable offer refused. I work from home so items can either be picked up in person or i can ship to location. Email me at email@example.com for pics.
