Description
This stock adapter for the semi auto M11/9, M11/NINE or M11A1 380 gun will allow you to use a stock or brace that uses the 1913 Picatinny Rail spec. The SIG SAUER Telescopting/Folding Stock, MCX, MPX is pictured and works well with this stock adapter. The stock adapter is made of carbon steel and parkerized in the traditional finish of the MAC series gun and comes with all the hardware needed to secure the stock adapter firmly into place. In order for this to fit your lower receiver, the bottom rear of the lower receiver must have three holes. The bigger of these holes is what holds the adapter in place. On some lowers, there is a welded rounded piece for a sling. Our adapter will still work for this style, but it must first be modified. Please let us know if you have this style of lower receiver and we will make the necessary modification before we ship it to you.
Note: This stock adapter will not work on full-auto guns. Click here for the Full-Auto Stock Adapter. Stock not included. It is illegal to put a stock on a pistol. The gun must be registered as a Short Barrel Riffle (SBR) in order for it to be legal.
