Most 5.56 suppressors make an AR-15 run dirtier and spit gas back at you. The Dillon Rifle Company DRC556 was designed to fix that. This patterned black version is printed in one piece from Inconel 718 and uses Dillon's patented PIP venting to keep back pressure low, so your AR stays cleaner and your eyes stay drier.
At 5.375" long it's a compact can that keeps an M4-length rifle handy, and the Inconel body shrugs off the heat of fast shooting and short barrels. It mounts on the 1.375x24 HUB standard and ships with a 1/2x28 direct-thread mount, the most common AR-15 muzzle thread. The black Cerakote carries Dillon's raised logo pattern.
Dillon Rifle Company designs and builds its suppressors in Phoenix, Arizona, about a half hour from our Mesa shop, so this is a locally made can you can see and buy in person.

Good to know

- Suppressor covers fit as long as they don't cover the first row of vents or logos.
Questions we get about this can
Will it fit my AR-15?
Most AR-15 barrels are threaded 1/2x28, and that mount is included. Bring the rifle in and we'll confirm the thread and install it.
Is it good on a short barrel?
Yes. Inconel handles the extra heat and pressure of short barrels, and the low back pressure helps SBRs run cleaner.
Can I shoot .223 Rem through it?
Yes. It's rated for 5.56 NATO and .223 Remington.
