Description

Our Alpha UltraFlash slim flash suppressor has a sleek, modern look and is slimmer than a standard mil-spec A2 — but is much more effective while reducing unnecessary bulk.

•  Works with 5.56mm up to .30 cal. — and everything in between such as 6mm ARC and 6.5 Grendel — if the barrel is threaded for 5/8-24
•  Makes a 14.5″ barrel — when pinned and welded per ATF specifications — a non-SBR (Short Barreled Rifle) of over 16″ in length
•  Slim, low-profile diameter allows a .750″ gas block to slide over for installation and removal convenience
• Three-prong design beats all in test after test
•  Black nitride finish for all-weather durability
•  Fits 5/8-24 muzzle threads
•  Length: 2.25″
•  Weight: 1.85 oz.

Includes our UltraShims muzzle-device-timing, super-thin washer kit — a $4.95 value!

INSTALLATION NOTES: The ultra sleek look of our muzzle devices can make you wonder where to put your wrench, but the scalloped "tear-drop" cuts serve as wrench flats. Some use any tool — tape-wrapped — that can slip INSIDE the device through the slots in order to apply light torque.

The first step to install your REXUS Ultra muzzle device with your desired orientation, or "timing," is to get the desired thickness of muzzle shim(s). A quick method is to screw on the muzzle device until it bottoms out against the barrel shoulder, and then back it off until the muzzle device is oriented, or "timed," as desired — and then back it off again from roughly 12 o'clock to 11 o'clock, which will account for final tightening after hand tightening. Into the resulting gap between the barrel shoulder and the rear face of the muzzle device, slip an edge of a shim(s) that fill that gap. With this knowledge, proceed to install the muzzle device with shims. There will be a bit of trial and error, but this method is a quick way of getting you close.

Before installing the muzzle device, put the same moly-lithium grease on your barrel's muzzle threads as you put on your receiver threads when installing a barrel. After you slip on the desired thickness of muzzle shim(s), also grease the rear face of the muzzle device so it is lubed as it contacts the shim face.

To tighten, wrap your wrench jaws or other tool in tape so they don't mar the surface, and then tighten the muzzle device only just snug past hand tightening, roughly the distance from 11 o'clock to 12 o'clock. Don't need to crank on it like you would with a crush washer; this prevents distortion which could affect accuracy.
