SIG SAUER MCX Rattler 300 AAC Blackout with Tailhook Upgrade



A Pistol Cannot Get Cooler.


Compact, tactical and gorgeous, you might just have to find a way to make this your everyday carry. Throw on a sleek backpack and this is your private security team. The SIG SAUER MCX Rattler in 300 AAC Blackout with a Tailhook Upgrade is the ultimate pistol. The telescoping tailhook brace diminishes size when not needed. It then rapidly deploys at your desire. Additionally, the ambidextrous controls ensure operational abilities at a moments notice under any circumstances.

Chambered in 300 AAC Blackout, the MCX Rattler comes chambered and ready for best use as a Personal Defense Weapon (PDW). As a nice feature, the MCX’s barrel can be swapped for a 5.56 NATO barrel, allowing the 5.56 NATO for use during practice and an easy switch back to 300 AAC Blackout for use as a PDW. And of course, the MCX Rattler is equipped with an M-LOK handguard for all the best accessories. This is the best choice for shooters desiring to be fast-deploying operators.


SIG SAUER has set a standard for the gun world. They are quality in quantity. They have innovated several fields when most companies struggle at one. Owning SIG is owning a product that has been tested through time and torture to bring about the most revolutionary and quality firearm you can own. Never settle.
