Just returned from four days at the Black Dog Gun Range down in Celina, TN, and their first machine gun shoot. We really had a great time! We were able to fire a Thompson, UZI and a Barrett .50 cal. all three firsts for me and my son. We really enjoyed the opportunity that we had to educate people about the importance of shooting protection. I know those that purchased custom earplugs from us at the event will enjoy them for years to come.
