This was my first time ordering from Midwest Optics. I placed order for this BCG on a Sunday morning. It shipped out first thing Monday morning with tracking # and I received it Wednesday afternoon. Bcg came well packaged. Sionics Bcg looks awesome. Compares to my Sons of Liberty carrier but has the OCKS screws well staked. I hadn’t seen any other reviews here or much on Midwest Optics and I took a chance. So glad I did. I have only found a few places with this kind of excellent service is why I am leaving this review and wanted to comment about my experience.
