The venerable US Army M24 Sniper Weapon System, in service since 1988, has seen various attempts at modernization over its three and a half decades. These efforts, including the XM24A1, M24A2, M24A3, and M24E1, predominantly focused on cartridge upgrades from the 7.62x51 to .300 Winchester Magnum or .338 Lapua Magnum, with only one integrating a chassis system. Recognizing the potential for a more comprehensive upgrade to existing M24s, the Israeli Defense Force (IDF) partnered with MDT in 2019 to create the IDF Modernized M24 SWS program, as first reported by rifleshooter.com.

The IDF's approach was straightforward: replace the original fiberglass stock with an MDT chassis, upgrade the optic and mount, and add a muzzle brake. The rifleshooter.com review, focusing primarily on the MDT IDF Modernization Program Chassis, also noted visual cues suggesting that the rifles’ barrels were reset and chambered during this process. The rationale for this upgrade extends beyond static range performance; while the original M24s maintained accuracy under ideal conditions, the modern battlefield demands more, particularly in night operations and improvised field positions.

The new MDT chassis delivers significant improvements critical for contemporary precision rifle use. It allows for full integration of night vision optics, lasers, and illuminators, crucial for low-light engagements. The system also incorporates a detachable, AICS-style magazine, a substantial upgrade from the M24's internal box. Furthermore, the chassis features a heavy-duty folding stock and extensive adjustability, including length-of-pull, cheekpiece height, butt plate position, and even side-to-side cheekpiece movement, ensuring optimal stock weld and fit for various shooters and larger optics.

Key features of the MDT IDF Modernization Program Chassis include a robust, beefy fore-end designed for rough duty, diverging from the LSS-XL. It boasts a secure night vision rail attached with four large screws and two alignment pins, offering MLOK slots for accessories. Around the pistol grip, a removable ambidextrous thumb shelf supports different shooting styles. The wide trigger guard accommodates gloved hands and includes a slot for debris and water drainage. The hinged folding mechanism is strategically designed to fold against the bolt handle side, minimizing the rifle's overall width when stowed. The oversized rubber pistol grip enhances ergonomics and control.

During testing, a well-worn M24 SWS was upgraded with the MDT chassis, a Nightforce ATACR 4-16x50 in a Spuhr mount, and a Harris bipod. The modernized system offered improved feeding, comfortable ergonomics, and easy positional settling. Accuracy results were impressive, with a 5-round group at 100 yards measuring .497 inches (.475 MOA) using Federal Gold Medal Ammunition, and a best 100-yard group of .209 inches (.200 MOA) with 175-grain SMK handloads. This project successfully brings the M24 into the modern era, providing night vision compatibility, enhanced ergonomics, optic versatility, and increased accuracy without necessitating a complete replacement of the core weapon system.
