If you were looking for an effective Personal Defense Weapon that is super versatile and fun to shoot at the range, a Short AR-15 is an excellent option. AR pistols and SBRs are very popular these days, and you can see why. They offer better accuracy and range than a pistol and have the firepower of a rifle in a very short and easily maneuverable platform.

However, keep in mind that the shorter the barrels, the more concussive and violent the muzzle flash will be, especially when you are firing rifle calibers out of a smaller platform. The muzzle flash, caused by unburnt powder, and expanding gasses, can make it difficult for the shooter to focus on their target.

Installing a flash hider can quickly fix this problem. Flash hiders are designed to disrupt and disperse the expanding gasses and unburnt powder coming out of the barrel, eliminating the chances of combustion outside the barrel. The 3FO-S Short Flash Hider by Breek Arms is an excellent option. This flash hider is designed for 5.56 and .223 rifles, and it is very effective and eliminates muzzle flash. Made from 4140 Prehard Steel, this flash hider has a 3-prong design, with threads on the indie, which help disrupt the gasses.

Moreover, this flash hider also has threads on the outside, designed to accept other Breek Arms muzzle devices over this flash hider. For instance, the Breek Arms Castle Blast Can is an excellent muzzle device for small concussive firearms that can be installed over the 3FO-S Short Flash Hider.

So, whether you have a rifle, AR pistol, or SBR, the 3FO-S Short Flash Hider by Breek Arms is an excellent option for any 5.56 or .223 firearm.
