The Sig Sauer MCX 5.56 with an 11.5-inch barrel is a short-barreled rifle (SBR) built for operators who need serious capability in a genuinely compact package. This folding MCX delivers the accuracy and reliability Sig Sauer is known for in a form factor that handles vehicle storage, close-quarters work, or tactical readiness without the bulk of a standard rifle. The 5.56 NATO chambering pairs with a 30-round magazine capacity, giving you common caliber availability and combat-proven magazine compatibility wherever you operate.
The 11.5-inch barrel hits the balance point between velocity retention and maneuverability—short enough for tight spaces and vehicle work, long enough to maintain functional range and ballistic performance. The folding stock design collapses the overall length even further, critical for anyone working from vehicles, aircraft, or confined spaces. Black anodized finish means the rifle handles hard use without advertising itself, and the MCX platform is known for smooth ergonomics and low recoil impulse thanks to its short-stroke piston system.
If you're in law enforcement, private security, tactical response, or other professional service roles, Sig Sauer's OFF-DUTY program is designed to support you with professional-grade equipment. This MCX SBR represents serious engineering for serious work—not a range toy or entry-level carbine, but a rifle built to perform under pressure with the ergonomics and controls that let you work fast and accurately when it matters.
| Caliber | 5.56 NATO |
| Barrel Length | 11.5 inches |
| Configuration | Short-Barreled Rifle (SBR), folding stock |
| Magazine Capacity | 30 rounds |
| Finish | Black anodized |
| Operating System | Short-stroke piston |
| Brand | Sig Sauer |
This is an SBR (short-barreled rifle) configuration. Ownership requires registration with the ATF and a valid Form 4 stamp. We cannot ship SBRs across state lines; you must be a compliant owner before purchase. Check your state and local laws before ordering.
An 11.5-inch barrel on the MCX keeps velocity and energy suitable for 5.56 duty work while delivering a notably shorter overall footprint—especially critical with the folding stock extended. This length is a working compromise for professional users who prioritize maneuverability in vehicles, aircraft, or building entries without sacrificing too much ballistic performance.
The MCX 5.56 accepts standard AR-pattern 5.56 NATO magazines, including the supplied 30-round magazine. This means compatible magazines are widely available and often already in inventory for 5.56 shooters.
OFF-DUTY is Sig Sauer's program to provide exclusive pricing and equipment support to qualified American professional service members—law enforcement, military, first responders, and related roles. Eligibility and terms are managed through Sig Sauer directly.
