Does this fit MPX K gen 2 Nobel? Expert Answer

No, it unfortunately would not.

MPX handguard by Average shooter, Verified Owner, December 11, 2024
I purchased this handguard to cover my OMEGA 9K which I mounted on my SIG MPX K. With the 4.5” barrel and suppressor it almost covers the whole assembly. The handguard lines up and locks in just like the stock one with very close tolerances.

stripped screw by Ken, Verified Owner, June 30, 2026
Overall nice product but one of the screws that is used to secure my hand guard and prevent any slop/play came to me stripped. Resulting in a relatively loose guard until I order a replacement.
