Frequently Asked Questions

What are the main pros of the SIG MPX according to the review?

The SIG MPX is praised for its excellent Timney trigger, modern and user-friendly magwell design that aids in reloads, and a very manageable recoil impulse that makes it fun to shoot and 'shred' with. Its AR-style ergonomics are also a significant plus.

What are the primary criticisms of the SIG MPX in this video?

The main criticisms include its considerable weight, estimated around 5 lbs base, and the retractable brace being too short, leading to a limited length of pull. The reviewer also notes a lack of MLOK slots on the older model's front end.

How does the SIG MPX compare to the MP5?

The SIG MPX is described as a 21st-century reboot rather than an MP5 clone. It was designed to replace the MP5, incorporating features like a short-stroke gas piston, closed bolt, and AR-style ergonomics for improved reliability, low recoil, and suppressor use.

What is the recommended red dot placement on the SIG MPX?

Due to the firearm's short length of pull, the reviewer recommends mounting the red dot further forward than might seem conventional. This placement prevents the optic from dominating the field of view and allows for better dot acquisition.
