When applying for an NFA firearm, you must submit your ATF paperwork, NFA Gun Trust, 5320.23, etc. But when will your tax stamp application be approved?
The shutdown will also affect the Bureau of Alcohol, Tobacco, Firearms and Explosives, meaning if you wanted a gun permit, you'll have to wait until the shutdown is over.
Supression: Silencers reduce the noise by giving gases a larger, contained space to dissipate and cool before exiting. Internal baffles (1) divide the silencer into various expansion chambers (2) for maximum efficiency.
Very interesting to see what a silencer actually looks like being fired with a see through silencer. You can actually see the exhaust gasses expanding into the chambers within the silencer.
We fired 700 rounds in one continuous burst through a full-auto M249 saw. The can ended up breaking around the 350-400 round mark. The gun itself ran wonderful and had no problems.
After firing there is a high-pressure of expanding gas from the propellant. The suppressor consists of a series of chambers, which captures the high-pressure gas, giving it space to cool and dissipate.
