SIG Sauer Stock Adapter - 1913 Interface Folding Knuckle

For decades, one thing that has bothered people using an AR platform is how hard it is to make a folding stock that works well. Thanks to the buffer tube, this has been nearly impossible. But now, there are solutions to these problems that the market as begun to offer. 

One such solution is the MPX and MCX offered by Sig Sauer. Coming in a variety of configurations and calibers, these two platforms make it possible to use a similar platform to the AR in terms of handling, but in a smaller package. One thing that both of those platforms share is that hey have a section of 1913 rail on the back. That’s where the SIG Sauer Stock Adapter - 1913 Interface Folding Knuckle comes into play.

With this adapter, you can take a standard section of 1913 rail, such as the one on the back of the MCX, MPX, and a growing number of similar firearms as the industry catches up with this idea, and attach a standard AR buffer tube, on which you can attach a stock. There are some things to keep in mind here, though. First is to make sure to comply with any state and local laws. Second, when you attach a stock to your newly installed buffer spring with the SIG Sauer Stock Adapter - 1913 Interface Folding Knuckle, make sure that you do not, for example, accidentally make a Short-Barreled Rifle and run afoul of the ATF. That said, if you’re looking for a good way to mount an appropriate stock in a folding configuration, this is the tool for you. The SIG Sauer Stock Adapter - 1913 Interface Folding Knuckle is the new standard in folding stocks.
