Product DescriptionThe Yankee Hill SRx Quick-Detach (Q.D.) Flash Hider is a sleek, low-profile muzzle device built for shooters who want a clean suppressor-ready setup without extra bulk or complexity. Designed for the YHM SRx (Suppressor Rx) system, this long flash hider features a black phosphate steel construction and an internal taper seal positioned ahead of the threads to help lock the suppressor in place and create a tight gas seal during use. The taper seal helps keep gases and debris from building up on the threads for more consistent mounting and easier maintenance. This flash hider is intended to be used with the YHM SRx Adapter (YHM-4400) and supports an industry-standard HUB (1-3/8 x 24) mounting interface when paired with the SRx adapter.Product Highlights SRx system Q.D. flash hider designed for a sleek, low-profile suppressor mounting setup Internal taper seal helps provide consistent mounting and helps keep threads cleaner during use No need to time or shim the muzzle device for installation convenience Durable steel construction with black phosphate finish for wear and corrosion resistance Made to pair with the YHM SRx Adapter (YHM-4400) for HUB (1-3/8 x 24) compatibility Specs Brand: Yankee Hill Manufacturer Part Number: 440528 UPC: 841812101543 Product Type: SRx Quick-Detach (Q.D.)
