9MM AR Flash Hiders

9MM AR Flash Hider options are not quite as plentiful as a .223/5.56 AR-15. Fortunately though most of the choices are very good in that they are quite effective and visually appealing. Some 9MM AR Flash Hiders are meant to also function as an attachment point for a 9MM sound suppressor while others are simply 9MM AR Flash Hiders or 9MM Muzzle Breaks.


What You Need To Know

When selecting the your 9MM AR-15 parts absolute attention and consideration must be paid to your barrel and muzzle device selection. This is for compatibility and personal safety. Special attention must be paid to three areas. The three areas are the AR flash hider bore and flash hider threads and the barrel muzzle threads.

Caliber Bore Diameter – A 9MM bullet measures .355 diameter while a .223/5.56 bullet measures .224 diameter. Firing a 9MM bullet through a barrel fitted with a flash hider designed for .223/5.56 can have catastrophic results to the shooter and gun. Unfortunately there is no manufacturing standard with regards to 9MM Flash Hider and 9MM AR barrel threads. 9MM AR Flash Hider are available in the AR-15 standard 1/2″-28 configuration as well as 1/2″x32, 1/2″x36 and 5/8″x24.


9MM AR Flash Hider Thread Types -1/2x36, 1/2x32, 1/2x28, 5/8x24

Some AR flash hider and barrel manufacturers smartly thread their 9MM Flash Hiders 1/2″x36 and the less common 1/2″x32 threads per inch. The AR-15 standard flash hider for .223/5.56 is threaded 1/2″x28 threads per inch. In my opinion any threading other than 1/2-28 is a good safety precaution. This prevents the installation of a standard 1/2x28 AR-15 flash hider on a 9MM AR.

Note:Some manufacturers take am alternative approach. Their 1/2x28 flash hiders are bored to .375″ to be used with 300 Blackout or 9MM calibers.


What’s the Best 9MM AR Flash Hider?

What’s the best 9MM AR Flash Hider? Of course there is no singular answer to this question. Before we tackle that let’s get something else out of the way. If your 9MM AR plans include a 9MM sound suppressor aka silencer your options are extremely limited. You need a flash hider that is compatible with your 9MM sound suppressor. Most likely you will have exactly one flash hider to choose from. That will be the best flash hider for you. Note: reminder make certain your AR barrel choice and flash hider threads match!

AR 9MM Flash Hider Designs – As I stated previously in the category of 9MM Flash Hiders for AR rifles there are not a lot of choices, well not as many as the .223/5.56 counterparts. It’s not a bad thing though. Most 9MM flash hider designs are based off a few tried and true time tested designs such as the Smith Vortex Flash Hider, Three Prong Flash Hider, Four Prong Flash Hider and A2 Flash Hider. They all work well. You might instead decide to base your decision on style and finish for aesthetic reasons.

Advanced Armament AR-15 Blackout Non-Silencer Mount 9MM AR Flash Hider

The Advanced Armament AR-15 Blackout Non-Silencer Mount 9MM AR Flash Hider is a welcome edition to the 9MM AR-15 market. It’s a typical three prong vortex design. I am a big proponent of AAC sound suppressors and Blackout Flash Hiders. What makes this 9MM flash hider special is that is not a quick detach mount (QD Mount) for an AAC silencer. See an AAC Blackout QD Mount AR Flash Hider here on our 300 Blackout AR Rifle Project.
