The US Army M24 Sniper Weapon System, in service since 1988, has long proven its reliability, yet its original design has become dated. While the US Army explored various upgrades—including cartridge changes to .300 Winchester Magnum and .338 Lapua Magnum, and limited chassis integration with the M24E1—the Israeli Defense Force (IDF) took a different approach in 2019, partnering with MDT to develop a modernized M24 SWS package, as reported by rifleshooter.com.
The IDF's modernization strategy was direct: replace the original fiberglass stock with a purpose-built MDT chassis, upgrade the optic and mount, and add a muzzle brake. While rifleshooter.com focused primarily on the chassis, it noted that barrels appear to have been reset and chambered as part of the process, though specific details on the new Leupold optics or muzzle brake were not available to the author. This comprehensive upgrade addresses critical needs in modern combat, particularly for night operations and engagements from improvised field positions, where the legacy fiberglass stock presented limitations.
The MDT IDF Modernization Program Chassis provides full integration of night vision optics, lasers, and illuminators. It also enables the use of detachable AICS-style box magazines, a significant improvement over the M24's internal box. The chassis features a heavy-duty folding stock, crucial for transport and maneuverability, which folds against the bolt handle side to maintain a narrow profile. Ergonomically, it offers extensive adjustability for length-of-pull, cheekpiece height and lateral position, and butt plate, ensuring a proper stock weld with varying optics and shooter sizes. The design includes a robust night vision rail, attached with four screws and alignment pins, complemented by MLOK slots on the fore end for accessories. Further enhancements include a removable ambidextrous thumb shelf and a wide trigger guard to accommodate gloved hands, with a slot for debris escape.
For testing, rifleshooter.com equipped a personal M24 with the MDT chassis, adding a Nightforce ATACR 4-16 34mm scope in a Spuhr mount and a Harris bipod with POD-LOK. The author praised the system's robust construction, comparing its central structure to the LSS-XL chassis but with enhanced rough-duty features. Performance testing revealed impressive accuracy: a 5-round group at 100 yards with Federal Gold Medal Ammunition measured .497 inches (.475 MOA), and handloads with 175-grain SMKs produced a .209-inch (.200 MOA) group at the same distance. This project successfully brings the M24 into the modern era with enhanced ergonomics, night vision compatibility, and increased precision, all without replacing the core weapon system.
