HUGHES suppressors are made of premium materials so they are very strong and will last an extremely long time. There are no moving parts to wear out. In most cases a suppressor will outlast the barrel life of the host firearm. We have examples of centerfire rifle suppressors that have had over 75,000 rounds fired through them. We have examples of submachine gun suppressors with over 50,000 rounds fired through them. We use a precision machined mono-core baffle system made from various metals for long life.
