I noticed their free shipping is for orders $100 or more before tax not after.

I've had nothing but great experiences with these. I run these bcgs in all three of my ars no problems. Their knowledge, expertise, and promptness goes a long way. Their customer service is by far the best in the industry.

I bought this bcg along with my Triton Upper. I've tried many other value bcg's around the same price range and this by far had the best finish. 1000rnds later I've had no issues and the finish is still on point.
