I am in the process of trying to find a mossberg 590a1 on gunbroker. There are plenty of options. I was looking for a particular model tho, item #51660. regular synthetic stock, bead sights, 8+1 capacity, tang safety, 20" barrel. However it seems that this model is hard to come by. All i can find is the model with the heat shield and speedfeed stock. Does anyone have experience with this stock? Is it worth the extra bit of cash? This is basically going to be a home defence gun. Thanks for the input!
