The Monarch Recce was purposely built for AR Enthusiasts. We at FOR Systems used DMLS 3D Printing technology to concoct the best possible 5.56 offering on the market. The Recce boasts impressive sound suppression for a miniscule 4.9� frame. It doesn�t create the high levels of sound reduction at the cost of backpressure either. The Recce accomplishes this by using our �Active Transport� Mesh structures to diffuses high Pressure Gasses without building undo backpressure. This isn�t a run of the mill K can either because flash suppression on this little fella is superb. Even on SBRs lengths like 10.5, 11.5 or 12.5� rifles. Inconel construction also means it can handle anything you throw at it shy of actually shooting the unit. The Monarch Recce is the ideal 5.56 suppressor for all AR owners
