Product Description

What's in the Box

  • SIG MPX Copperhead 9mm
  • (1) 20-Round Magazine
  • Cable Lock
  • Owner's Manual

The MPX Copperhead features a monolithic Elite Series hard coat anodized upper receiver, with an integrated stock knuckle lower, and a 4.5” barrel. The MPX Copperhead comes equipped with the new SIG SAUER Pivoting Contour Brace (PCB) giving pistol users a brace that easily adapts to the movement of the shooter's arm with a patented swivel operation for perfect placement, and can be rapidly deployed.

Unconventional design, unmatched performance, and familiar AR handling. The SIG MPX redefines the submachine gun category with a new level of operator safety, in-field adaptability and proven reliability in the harshest environments. Completely ambidextrous, the SIG MPX is great for left- or right-handed shooters with its dual-sided selector switch, magazine release, charging handle and bolt release. The SIG MPX operates from a fully-closed and locked rotating bolt, offering enhanced reliability and safety in use. A short-stroke gas piston allows the SIG MPX to run all weights and brands of 9mm ammunition with no adjustments to the gas valve.

(5 out of 5) Order# 4620883 - SIG SAUER Low Profile QD Socket 1913
by George from Pinecrest, FL on June 26, 2020

The MPX arrived yesterday by late afternoon, and everything was in perfect condition, no complaints but one, the Low Profile QD Socket 1913 was missing, nowhere to be seen. According to Sig Sauer description of what is included in the box of Sig Copperhead PMPX-4B-CH, the Low Profile QD Socket 1913 should have been included. Can you please ship one out to me, so I can use my 2 points QD Sling Thank you.
