(4 out of 5) A happy customer
by from Washington, PA on

In times where a guy just wants to go shoot some jugs and stuff and ammo is so hard to find because of the scavengers this superstore loves up to its title. A little pricey on the ammo but considering the availability its understandable. A future customer you've made of me.

(5 out of 5) Sportsmans Outdoor in a pinch

In these times when ammo is hard to get, Sportsmans Outdoor came through.

(5 out of 5) Will buy from them again
