Sig Sauer MCX Rattler Virtus .300 Blackout 5″ PDW
5.5″ barrel SBR with M13 style skeleton stock
.300 Blackout is quickly becoming the go-to round for personal defense.
Designed for Special Operations, the short barrel MCX Virtus combines performs, concealabilty and reliability. A 5″ barrel is ideal for to add a suppressor. The M-LOK handrail provides ample space for weapons lights and other accessories.
The Sig MCX Rattler has now been renamed as the Virtus SBR, but whatever you call it, it is downright awesome.
Note: Video is a little dated and refers to the SBR as the Rattler, and shows the pistol brace version, which is no longer offered, only the SBR
Rapid deployment, thin, agile, and precise. This is the MCX Rattler Virgus. Featuring a 5.5″ PDW barrel, the MCX platform has never been more compact or accessible. Ready to go where-ever it’s needed, the MCX Rattler Virtus has a thin, foldable stock for easy concealment and stowage. This gun was designed from the ground up to be as discrete as possible while retaining all the capabilities of the MCX. Free-floating M-LOK handguards matched with a PDW upper and a PDW Ultra Thin Folding Aluminum Stock, the MCX Rattler Virtus SBR is the ideal choice for fast-moving operators.
The MCX from SIG SAUER is engineered for adaptability, sound suppression and longevity. Cold hammer-forged barrels are user-changeable, offering the utmost in mission-specific flexibility. SIG’s internal recoil system offers reduced recoil and a compact platform. The MCX VIRTUS SBR features the new Matchlite Duo trigger for crisp, clean feel. Free-floating M-LOK handguards provide the optimal configurability. Ambidextrous, AR-style controls and a folding stock enable the MCX RATTLER VIRTUS SBR to be tailored to the shooter and the environment. The M13 style stock adds to the versatility and concealability of the rifle.
Based upon a request from the US Military to replace the MP5, the Sig MCX features a short-stroke recoil system with gas operated piston. This design removes the need for a buffer tube, thus allowing for a shorter PDW. The gas regulator has two positions, to move from suppressed to unsuppressed. The 5/8×24 thread pattern allows for easy installation of a .30 cal direct thread suppressor, or go crazy and add a three-lug adapter.
The VIRTUS line from Sig allows for barrel swaps and handguard swaps. So, this .300 Black Out can swap to be a 5.56mm rifle, and if you prefer a longer barrel, the .300 BLK is also offered in 9″ with more handguard space to accommodate extra accessories.
