The 3FO-S Flash Hider is machined out of heat treated 4140 then nitrided offering exceptional strength and reliability. The primary function of the 3FO-S diminishes muzzle flash by dispersing and redirecting the escaping gases generated by the fired round, thus minimizing the signature flash produced at the muzzle maintaining your tactical advantage in critical situations as well as keeping your rifle footprint as small as possible.
The 3FO-S has internal threads, a significant design advantage offering even more flash suppression over standard flash hiders. The reduced flash not only helps maintain a clear sight picture but also reduces the chances of the shooter being temporarily blinded in low-light conditions, ensuring optimal visibility and target acquisition. It features a sleek, short profile that integrates seamlessly with your system, maintaining a clean and streamlined appearance.

Breek Arms’ lineup of Outside Threaded Muzzle Devices is an affordable upgrade that gives you the option to run a flash hider or muzzle brake while utilizing our Breek Arms Castle Blast Shield as a forward blast diverter or concussion device. Simply slide the Blast Shield over the outside of the muzzle device and turn the blast shield on. This gives the shooter a more pleasant experience when firing especially for shorter platforms that tend to have an overbearing concussion. Added durability due to an updated heat treating process that increases reliability for higher muzzle pressures. Installation of all Breek Arms muzzle devices are very straightforward and require basic hand tools.

3FO-S FLASH HIDER SHORT
Great little flash hider for a short PCC set-up. Breek Arms seems to have a solid option or two for about any caliber you can think of...

Best bang for the buck!!
First off, let me say that this is my first time using Breek Arm's products. I purchased the short flash hider and castle deflector together. Installation onto the barrel was a breeze, forks timed perfectly (preference, not a requirement). After seasoning the threads a few times the castle cover fit like a glove, easy on/off with some elbow grease (no wrench required). Once at the range the short flash hider performed better than expected, flash was basically non-existent and the recoil wasn't anything worse than an A2 cage. Gases out the forks were manageable and didn't affect muzzle rise. Once I installed the shield the recoil jumped a bit but that's understandable as to it's design it blows everything out the muzzle directly to the front, so physics still played it's part. Overall this will be my permanent addition to my home defense rifle, if you're looking at this to be a future upgrade for yourself I recommend you take the plunge. Packaging was awesome, they gave a sticker decal and a thank you card which is greatly appreciated.

Short Flash hider 9mm
Used on a 16" PCC build to make an already quiet rig even quieter. Works great.

3FO-S FLASH HIDER SHORT OUTSIDE THREADED - .223/5.56, 9MM
Quality wise this thing looks good, but the main reason I bought it was because of the blast shield attachment option. The look of the two together is awesome. Can't speak for functionality since I haven't been to the range yet, but I don't forsee any issues.

Amazing looks
It’s small and does the job while keeping the rifle looking badass. Definitely would recommend if someone is looking to shorten their muzzle break. It pares nicely with their blast shroud.
