LMT DEFENSE 5.56 NATO 4 PRONG FLASH HIDER 1/2X28 THREAD

The LMT Defense 5.56 NATO 4-Prong Flash Hider 1/2x28 Thread is a rugged, suppressor-ready muzzle device engineered to deliver exceptional flash suppression, reduced blowback, and reliable performance in a compact package. Designed for compatibility with the LMT ION Suppressor Series as well as HUB and Xeno-compatible suppressors, this precision-machined flash hider features an advanced taper lock gas seal that enhances sound suppression, reduces flash signature, and minimizes gas blowback when paired with a compatible suppressor. Its secure mounting interface also helps reduce the likelihood of carbon lock, especially when used with LMT's RMSTD and RMSTDT suppressor bases, ensuring dependable attachment and easier suppressor removal during extended use.

Manufactured from high-strength 17-4 stainless steel and finished with a durable Black Nitride treatment and C-192 Armor Black coating, the 4-Prong Flash Hider is built to withstand extreme conditions and heavy firing schedules. Extensive testing to U.S. SOCOM, NATO, and MIL-STD standards validates its durability, reliability, accuracy, flash mitigation, gas management, and thermal performance across demanding operational environments. The precision-engineered design helps maintain consistent point-of-impact performance when used with suppressors, making it well suited for tactical, duty, and recreational shooting applications. Proudly made in the USA, this 1/2x28-threaded flash hider offers shooters a durable, lightweight, and highly effective solution for maximizing suppressor performance and long-term weapon reliability on 5.56 NATO platforms.
