The KAK Industry A1 Flash Hider, 1/2-28 (brand part no. 410-1702-015) is a retro-style muzzle device that threads onto a barrel cut for 1/2-28. It follows the classic A1 flash hider design, then adds heat treating and a phosphate coating for durability. Every piece is precision machined in house at KAK Industry, with milled flats so you can install it with a standard wrench. It suits builders who want the traditional look of an early rifle, or a simple, proven flash hider at a modest weight. A crush washer is not included.

Key Specifications
