We only email about once per week and we do our best to make sure they're worth your while.

Family Owned and Operated

We’re not a huge corporation that values the bottom line more than their customers and we’re not a one-man band selling AR15 parts out of a garage, we’re big enough to compete and small enough that each customer matters.

Satisfaction Guaranteed

Your AR15 build is important to you, so it is important to us. Our return policy is simple, if you’re not 100% satisfied with your purchase send it back within 30 days for a no-questions-asked refund.

World Class Service   ★★★★★ We're focused on doing business in a way that earns us life-long customers. We have a 99.8% Positive eBay and Stamped.io Verified Customer Feedback Rating.
