The M24 Sniper Weapon System, a steadfast platform in military service worldwide since 1988, has demonstrated remarkable longevity. However, its original design has become dated, leading to various modernization efforts over the years. The US Army, for instance, implemented several M24 variants—including those chambered in .300 Winchester Magnum and .338 Lapua Magnum—but only one of these iterations fully integrated a chassis system.
In 2019, the Israeli Defense Force (IDF) embarked on a distinct path to upgrade its existing M24 inventory. Collaborating with MDT, the IDF initiated a program focused on the IDF Modernized M24 SWS, with a new chassis at its core. This strategic approach involved replacing the rifle's original fiberglass stock with an MDT chassis, upgrading the optic and mount, and incorporating a muzzle brake. This targeted modernization aimed to revitalize the legacy platform for contemporary operational demands. While specific details regarding the chosen muzzle brake and Leupold optic model were not publicly detailed, observations of service rifles have indicated that armorer or gunsmith intervention was likely involved in resetting and re-chambering barrels during the upgrade process.
The central element of the IDF's modernization is the MDT chassis. The original M24, while proving accurate under static range conditions, posed limitations for modern battlefield requirements, particularly in night operations and dynamic field positions. The new chassis directly addresses these issues, providing full integration capabilities for night vision optics, lasers, and illuminators. It also introduces a detachable magazine system, a heavy-duty folding stock, and comprehensive adjustability, allowing it to conform to shooters of various sizes and preferences.
One individual, documenting an upgrade of an M24 with the MDT IDF Modernization Program Chassis, noted that both the disassembly of the factory M24 and the assembly of the new chassis were straightforward, reportedly taking only minutes. The rifle's action seamlessly bolted into the chassis, and the night vision and scope rails were securely screwed into place. The assembled rifle in this account was outfitted with a Nightforce ATACR 4-16x50 scope in a Spuhr mount. The chassis itself was described as one of MDT’s more robust offerings, sharing a foundational resemblance with the LSS-XL chassis but featuring specific enhancements tailored for demanding, “rough duty applications.” A Harris bipod with a POD-LOK was also added to the fore end, consistent with observations of IDF-issued rifles.
The night vision rail and fore end of the IDF Modernized M24 chassis are engineered for resilience. The night vision rail attaches to the fore end with four substantial screws and incorporates MLOK slots on its sides for mounting accessory rails. To ensure precise alignment, two pins at the front of the fore end engage securely with the night vision rail. Further ergonomic improvements include a removable ambidextrous thumb shelf located near the pistol grip, which was reported to effectively support various shooting styles. The trigger guard is generously proportioned to accommodate gloved hands and includes a drainage slot at the bottom to prevent water and debris accumulation.
A key design feature is the chassis’s hinged folding mechanism, which allows the stock to fold against the bolt handle side of the rifle. This specific folding direction is crucial for minimizing the rifle's overall width when stored or transported. When extended, the stock offers extensive adjustability, including length-of-pull, a sliding cheekpiece, and a butt plate. These adjustments are vital for maintaining a consistent and proper stock weld, especially when utilizing larger or higher-mounted optics.
Operational accounts suggest that shooting the IDF Modernized M24 with the MDT chassis provides a positive experience. Feeding from AICS-style box magazines is cited as a significant improvement over the internal box magazine system of the original Remington M24. The oversized rubber pistol grip supplied by MDT is described as providing a comfortable and full hand-fill, and with the rifle properly adjusted, achieving a stable shooting position is reportedly facilitated.
The modernization also appears to contribute to enhanced accuracy. For instance, a 5-round group fired at 100 yards with Federal Gold Medal Ammunition was recorded at 0.497 inches (0.475 MOA). Furthermore, load development using 175-grain Sierra MatchKing (SMK) bullets reportedly yielded a best 100-yard group of 0.209 inches (0.200 MOA), indicating a notable improvement in the rifle's precision capabilities.
Overall, the IDF Modernized M24 program is characterized as a successful initiative to bring the M24 into the modern era. It delivers night vision compatibility, improved ergonomics, broad optic compatibility, and increased accuracy without requiring a complete replacement of the core weapon system.
