The Forgotten SIG: MPX Copperhead vs MPX-K
This video provides a detailed comparison between the SIG Sauer MPX Copperhead and the MPX-K, highlighting their key differences in modularity, receiver design, and ergonomics. The presenter, who has owned these firearms for several years, notes the Copperhead's proprietary monolithic upper and fixed handguard as significant limitations compared to the MPX-K's modularity. The review also touches on the integrated brace system of the Copperhead and the differences in grip size and lower receiver aesthetics. The presenter concludes that the MPX-K is generally a superior platform due to its adaptability and modularity, making the Copperhead less desirable.
