Don't Shoot Your Silencer Without This!
This video explains the critical role of the Nielsen device (booster) for reliably cycling suppressed semi-automatic pistols with tilting barrels. Without it, the added weight of a suppressor prevents proper slide action, leading to malfunctions like stovepipes. The host demonstrates this failure on a Glock and highlights firearms that do not require a booster, such as fixed-barrel pistols and rifles.
