Frequently Asked Questions

What is the recommended cleaning kit for a Sig MPX?

The video recommends the Otis Defender Series cleaning kit, which is available for various calibers including 9mm. It's presented as a more affordable option compared to military configurations and includes essential tools like cables, brushes, and patch savers.

What solvents and lubricants are suggested for cleaning a Sig MPX?

The instructor prefers G96 Gun Solvent for its effectiveness against carbon and copper fouling, and G96 Gun Treatment as a preservative. Croyle oil is also mentioned for deactivating copper solvents and providing corrosion resistance. For field use, Otis O85 Smart Solvent is a good all-in-one option.

How do you properly disassemble the bolt carrier group of a Sig MPX?

Disassembly involves removing recoil springs and guide rods, then pushing inward on the bolt to release the firing pin. The cam pin is rotated and removed, followed by the bolt itself. The extractor is then removed separately.

What is a crucial step after cleaning and reassembling a Sig MPX?

A critical step after reassembly is performing a function check. This ensures the firearm operates correctly by verifying the safety mechanism, trigger pull in both safe and semi-auto modes, and the trigger reset function.
