SIG Rattler: Full Field Strip

Published on September 3, 2019
Duration: 8:04

This guide details the field stripping and basic maintenance procedures for the SIG MCX Rattler, as demonstrated by an experienced instructor. It covers the separation of receivers, removal of the bolt carrier group, and disassembly of key components like the firing pin and cam pin. The guide also touches upon the benefits of the piston system and considerations for aftermarket parts.

Quick Summary

The SIG Rattler can be field stripped by separating the upper and lower receivers via pivot pins, then removing the charging handle and bolt carrier group. Further disassembly includes removing the firing pin retaining pin, cam pin, and bolt. The piston system allows for compact, side-folding stocks, and caliber changes are possible by swapping the barrel and piston assembly using T27 Torx bolts.

Frequently Asked Questions

How do you field strip a SIG Rattler?

To field strip the SIG Rattler, first ensure it's unloaded. Separate the upper and lower receivers by removing the pivot pins. Then, remove the charging handle and bolt carrier group. Further disassembly involves removing the firing pin retaining pin, cam pin, and bolt. The handguard and barrel assembly can also be removed.

What tools are needed to disassemble the SIG Rattler?

For basic field stripping of the SIG Rattler, you primarily need a bullet tip to assist with the firing pin retaining pin and a T27 Torx key for removing the barrel and piston assembly. An aftermarket charging handle is also recommended for easier manipulation.

What is the advantage of the SIG Rattler's piston system?

The piston tappet system in the SIG Rattler eliminates the need for a traditional AR-15 buffer tube. This design allows for the use of compact, side-folding stocks (PDW stocks) and contributes to cleaner operation by venting gas away from the bolt carrier group.

Can the SIG Rattler change calibers?

Yes, the SIG Rattler can be adapted to different calibers, such as 5.56mm, using caliber change kits. This process involves removing the barrel and piston assembly using T27 Torx bolts and replacing them with the appropriate components for the desired caliber.
