Under ATF's October 9 policy, you can buy a suppressor on a 4473 in some states. We still recommend a Form 4: it stays compliant if the policy changes, and ATF approvals come back in days.
CANIK VOID 556K SUPPRESSOR - COMPACT, HUB-COMPATIBLE, 5.56X45MM AND 6MM ARC
The Canik Void 556K is the compact 5.56 suppressor in Canik's Void line, a HUB-compatible can for AR-15s and other 5.56 rifle platforms developed with and manufactured by Otter Creek Labs. It measures 5.1" long and 1.625" in diameter and weighs 12.3 oz. The 556K is built from heat-treated 17-4 stainless steel with a welded baffle stack and a high-temperature Cerakote finish. It's rated for 5.56x45mm on barrels as short as 7.5", and for 6mm ARC and other similar cartridges on barrels 10.5" and longer.
Both a solid front cap and a low back pressure front cap ship with the Void 556K. Running one or the other lets you choose your balance of sound suppression and reduced gas blowback, depending on whether the rifle is set up for precision shooting, hard use, or cleaner running on a semi-auto. Changing caps takes a wrench on the cap's wrench flats.
Mounting starts with the included 1/2x28 direct thread adapter, which threads onto common 5.56 barrels and seats against a 90-degree shoulder. If your barrel has a tapered shoulder, you'll need a tapered cap to create a 90-degree mounting surface. The rear of the suppressor is HUB (1.375x24) compatible, so it also accepts any HUB-compatible mount if you want to change mounting systems.
Prefer a longer can? The Canik Void 556 is the full-size 5.56 version at 6.1" and 14.9 oz. For .30 caliber rifles, take a look at the Canik Void 762.
CAPITOL ARMORY'S OPINION
The front caps are what we like most about the Void 556K. A lot of 5.56 cans give you one setup and leave you to sort out gas issues some other way, but Canik built the choice right into this one. Put the low back pressure cap on a semi-auto host and it's a real quality-of-life upgrade. Want a little more suppression? Swap to the solid cap, and you didn't have to buy anything extra to do it.
Where the 556K really makes sense to us is on a short-barreled AR-15. At 5.1" it keeps an SBR handy, and it's rated for 5.56 on barrels as short as 7.5", so it pairs well with the short builds people actually want to suppress.
We're also big fans of the mounting setup. The included direct thread adapter has you shooting right away on standard AR-15 threads, and because the 556K is HUB compatible, moving to a QD system later is easy and you're never stuck with a proprietary mount. Still deciding between the Void models? Our Canik Suppressor Buying Guide compares them side by side.
