LMT DEFENSE 5.56 NATO CLOSED TINE FLASH HIDER 1/2X28 THREAD

The LMT Defense 5.56 NATO Closed Tine Flash Hider 1/2x28 Thread is a premium muzzle device engineered to maximize flash suppression, sound mitigation, and suppressor performance on 5.56 NATO rifle platforms. Designed for compatibility with the LMT ION Suppressor Series as well as HUB and Xeno suppressor systems, this closed tine design helps reduce visible muzzle flash while enhancing the overall effectiveness of the host firearm and suppressor combination. Its precision-machined taper lock gas seal creates a secure mounting interface that minimizes gas blowback, reduces flash and sound signatures, and helps prevent carbon lock during extended use, particularly when paired with LMT's RMSTD and RMSTDT suppressor bases. The result is a highly reliable attachment system that promotes easier suppressor installation and removal while maintaining consistent performance.

Manufactured from durable 17-4 stainless steel and finished with a rugged Black Nitride treatment and C-192 Armor Black coating, the Closed Tine Flash Hider is built to withstand harsh environments, sustained firing schedules, and demanding professional use. The design delivers industry-leading accuracy with minimal point-of-impact shift and dispersion when used with compatible suppressor systems, making it an excellent choice for tactical, duty, and precision shooting applications. Extensively tested to military and NATO standards for durability, reliability, sound suppression, flash reduction, thermal response, and gas management, this 100% USA-made muzzle device provides dependable long-term performance on both semi-automatic and fully automatic firearms. Featuring standard 1/2x28 threading, the LMT Defense 5.56 NATO Closed Tine Flash Hider offers a compact, mission-ready solution for shooters seeking enhanced suppressor compatibility, improved weapon performance, and exceptional durability.
