A rifle needs a side rail for 24/7 duty use but the Microtech rifle is one that actually looks incomplete without something to cover up those shiny bolt holes. Even if you're just a casual shooter or collector, I think you will be impressed with this product. The tough matte black anodized finish on our STG rails will match the rifle's receiver perfectly. This rail is precision machined to exact Mil-Std 1913 Picatinny specifications by a US Govt Contractor. We guarantee this rail will never break or fail.
