The Liberty Precision Machine Duty 5.56: The LPM DUTY 5.56 was designed to provide high holistic signature reduction for both operators and bystanders on gas-operated firearms. This requires moderate gas blowback and sound to the shooter while maintaining a high level of muzzle sound suppression. A simplified version of our Torch 5.56/6mm silencer, the DUTY achieves a much lower price point and smaller size for budget minded shooters who are willing to tolerate slightly more back pressure and gas blowback. Tuning of the host weapon is recommended. LPM highly recommends AGAINST the CAT SPOOKY 1 flash hider as it results in premature baffle wear and excess flash out of the silencer. No other muzzle device we have tested has displayed these characteristics.
