Description:

CTS product line was developed primarily for the US Government / Professional Market. The civilian market is a secondary benefactor to this program. As such the QC standards and priorities (and features) are very different than that of a commercial market AR15 manufacturer. To the very overwhelming majority of shooters, this is a huge plus in the column. It makes their product and extremely attractive option for a civilian shooter looking for a higher standard of product.
