This is a brand new OEM Sig Sauer telescoping and folding stock for the SIG MPX and MCX. This may work with other firearms which have a standard picatinny section for attaching a stock, but we cannot guarantee fitment on those other firearms. This stock uses a standard mil-spec M4 tube.
All NFA rules apply when installing this on a MPX or MCX pistol. Magazine pictured is for demonstration purposes only and is NOT included.
