WHAT DOES EBR MINI 14 MEAN?

When solely collapsed, its duration measures just 39″. In addition, its compact measurement can make it effortless to move or retailer; when coupled with a suppressor, it results in being a lot less than 6 feet in whole size.This chassis has been built for Ruger mini-14 but I am unsure it's going to, and I had trouble discovering info about this.
