The Yankee Hill Machine sRx Mini QD Muzzle Brake 5/8×24 (brand part no. YHM-4401-MB-24) is the 5/8×24 version of YHM’s shortest sRx quick-detach muzzle device. It is meant for hosts with a 5/8×24 muzzle thread and it mounts a suppressor through the sRx taper interface. The body is only 1.1 inches long, so it adds little length or weight. Yankee Hill built the sRx line around a low profile and easy use, and each piece is made in the USA.

Key Specifications

• The muzzle thread is 5/8×24, so it screws onto barrels threaded to that common pitch.
• The device is 1.1 inches long, keeping the added length short.
• It adds only .475-inch to the barrel on barrels with .6-inch threads, according to Yankee Hill.
• The diameter is .9375-inch, a slim profile that stays close to the barrel line.
• It weighs just 1.024 ounces, light enough to leave on a rifle that rarely wears a suppressor.
• The material is 4140 steel, a tough alloy steel suited to muzzle devices.
• The finish is black, which matches typical rifle hardware.
• The bore opening is sized for 9mm (.390-inch) and smaller calibers, per the maker.
• The mount is timeless, so it needs no shim or clocking to the barrel.
• A taper in front of the threads gives consistent mounting, and there are no moving parts.
