It isn’t a secret that the standard collapsible stock on an AR-15 can be a bit on the weak side thanks to the pin that holds the stock in place. If you have ever had to mortar your rifle to clear a malfunction and forgot to collapse the stock you know what can happen. The new Magpul UBR Gen 2 is stronger and lighter than the previous version and gives your rifle the ability to withstand just about any punishment you put the stock through.
