Description

The 8.6 Blackout cartridge has carved out a serious following among hunters and suppressor fans, and Q built this flash hider specifically for that ecosystem. It does two jobs at once. Shooting without a can attached, it knocks down visible muzzle flash so you keep your sight picture. When it's time to go quiet, it becomes the Quickie Fast-Attach interface for Q's PORQ CHOP and Short Chop silencers, letting you snap a suppressor on and off in seconds without wrenching anything.

Built for the 8.6 BLK Ecosystem

This version is cut for 5/8×24 muzzle threads, which covers a lot of the 8.6 Blackout barrels out there. Q machined 13/16 inch wrench flats into the body, so installation is as simple as grabbing the right wrench and torquing it down to spec, around 40 ft-lbs with a dab of Rocksett on clean, degreased threads. No crush washer needed, no timing headaches. Worth noting: these flash hiders use a standard straight thread, not a tapered one, so double check what your barrel is set up for before ordering.

A Compact Mount That Earns Its Spot

At 2.13 inches long and a hair over two ounces, it adds very little to the end of your barrel, which matters on a hunting rifle you're hauling through timber or a bolt gun you want balanced. The steel construction is built for hard use, and the Fast-Attach shoulder gives your suppressor a solid, repeatable lockup every time you mount it.

Who Should Grab the Q 8.6 Blackout Flash Hider

If you're running a PORQ CHOP or Short Chop, or planning to, this is the mount that ties the whole setup together. And even if the suppressor comes later, you get a quality flash hider in the meantime that's already prepped for the upgrade. It's one of those parts you install once and stop thinking about, which is exactly what a muzzle device should be.

Frequently Asked Questions

Which suppressors work with the Q 8.6 Blackout Flash Hider?

This flash hider serves as the Quickie Fast-Attach mount for Q's PORQ CHOP and Short Chop silencers, both built for the 8.6 Blackout cartridge. Once the flash hider is torqued onto your barrel, either can mounts and dismounts in seconds. It's the intended interface for keeping those suppressors locked up tight with a repeatable point of impact.

Do I need a crush washer to install this flash hider?

No, and you shouldn't use one. Q recommends cleaning and degreasing your muzzle threads, applying Rocksett thread locker, and torquing the flash hider to about 40 ft-lbs using the 13/16 inch wrench flats. Skip the crush washer entirely, since it would interfere with the shoulder that indexes your suppressor.

Does the Q 8.6 BLK Flash Hider have tapered threads?

No. This flash hider uses a standard, non-tapered 5/8×24 thread. That's worth verifying against your barrel before you buy, since some 8.6 Blackout barrels are cut with tapered muzzle threads that require a different mount.

Can I run this flash hider without a suppressor attached?

Absolutely. It works as a standalone flash hider that cuts down visible muzzle flash, which is a real benefit with 8.6 Blackout loads in low light. At 2.13 inches and around 2.1 ounces, it won't throw off your rifle's balance while you shoot unsuppressed.
