Description
Running a suppressor across multiple rifles gets old fast if you're direct threading it every time. The Sylvan Arms SA223QD solves that problem the smart way. Thread one onto each of your .223 or 5.56 barrels and your compatible Sylvan Arms can moves between rifles in seconds. The ratchet notches machined into the device give the suppressor a secure mechanical lockup, so it stays put shot after shot instead of slowly backing off the way a direct-thread can under heat and vibration.
Built From 17-4 Stainless, Made in the USA
Sylvan Arms machines the SA223QD from 17-4 stainless steel, which is the right call for a part that lives at the muzzle and takes constant heat and blast. The black finish holds up to hard use and keeps the whole package looking clean on a modern build. At 3.80 inches long, it adds usable mounting real estate without turning your barrel into a flagpole, and the whole thing is manufactured here in the USA.
Flash Hider First, Suppressor Mount Second
Even if a suppressor isn't in your immediate plans, the SA223QD earns its spot on the barrel. On its own it works as a flash hider, taming muzzle flash so your eyes stay adjusted during low-light shooting. Installation is refreshingly simple too. The standard 1/2×28 thread pitch fits the vast majority of .223 and 5.56 barrels out there, and there's no crush washer or shim kit to fuss with. Just spin it on, snug it down with an armorer's wrench, and you're done.
Pairing the SA223QD With Sylvan Arms Suppressors
This device is the mounting interface for Sylvan Arms cans like the Osprey 5.56 titanium suppressor, and it also works with their .30 caliber Warthog if you like running one suppressor across different calibers. If you're building out a suppressor setup with more than one host rifle, picking up an SA223QD for each barrel is the easiest way to make swaps painless. It's a simple part that does its job well, which is exactly what you want at the end of a barrel.

Frequently Asked Questions
Will the Sylvan Arms SA223QD work without a suppressor attached?
Yes. On its own it functions as a flash hider, so you can run it as a standalone muzzle device and still have a quick-detach mount ready whenever you add a compatible Sylvan Arms suppressor down the road.
Which suppressors does the SA223QD mount?
It's designed for the Sylvan Arms suppressor line, including the Osprey 5.56 titanium suppressor and the .30 caliber Warthog. The ratchet notches on the device let the suppressor tighten down for a secure lockup. It is not a universal QD mount, so cans from other brands won't attach to it.
Do I need a crush washer to install the SA223QD?
No, and that's one of the nicer things about it. It threads onto a standard 1/2×28 barrel and tightens down with an armorer's wrench, no crush washer or spacers needed. That keeps installation quick and makes moving it between barrels less of a chore.
Will this fit my AR-15 barrel?
If your barrel is chambered in .223 Rem or 5.56 NATO with standard 1/2×28 muzzle threads, you're good to go. That covers the vast majority of AR-15 barrels on the market. Just double check your thread pitch before ordering, since some barrels use non-standard threading.
