Adams Arms Manimal Muzzle Device

The popularity of 14.5″ barrels on AR-15s is exploding. These barrels require the addition of a pinned and welded muzzle device in order to reach the 16″ minimum legal barrel length so it seems that there are suddenly several muzzle devices that are specifically designed for this purpose. However, none of them have taken the purpose built nature of their design as far as the Manimal flash suppressor from Adams Arms.

This photo from Adams Arms shows the Manimal (right) compared to a standard A2 flash suppressor.

The problem with pinning and welding a muzzle device is that it makes it impossible to take the gas block off the end of the barrel without destroying the muzzle device. So shooters were basically stuck with whatever gas block and hand guard that they chose at the time the muzzle device was permanently attached. Adams Arms solved this problem by designing the Manimal with a small enough outside diameter to allow a standard .750″ gas block to slip over it. Genius!

The device is similar to the extended A2 flash suppressors that are sold for the express purpose of being permanently attached. I do not have any time behind the Manimal but I can attest to the fact that this style of flash suppressor does indeed suppress flash fairly well and it does suppress muzzle rise a bit as well.

This Manimal isn’t on the Adams Arms site yet but I suspect it will sell very well once it is available.
