We always love hearing from our customers. Here are a few of our reviews!
“I just wanted to take this opportunity to thank Wes and his team for a job well done on my G36 conversion. The job they did is second to none and the communication between Wes and I was great! When it comes to customer service, they’re the best.”
“Just wanted to drop you a quick email with a pic of the finished product after my scope was added, on my Model LV. Again, thanks a lot, rifle is great! You guys did a fantastic job!! The Hensoldt Z24 scopes do fit well!”
“Your work was amazing! The instructor at my long rage shooting class loved the rifle and was able to ding the 600 yard target on the first shot. He was highly impressed. All in all, great day at the range and great class as usual. Thanks Black Ops Defense”
