    This is my second time purchasing this ammo to run in my 18” 1:8 Proof Research barreled AR. While the ammo itself is top notch, yielding sub-MOA accuracy out to 600 yards, it was Gorilla’s customer service that prompted me to come back and write a review. They emailed out a 20% off code while part of their team was out at SHOT Show, so I took them up on a great deal, thinking it would take a week or more to ship. Nope! They had it out the door headed my way the very next day! Well done guys, keep up the good work, and we’ll keep coming back for sure!
