Yankee Hill Machine Co Nielsen Booster Assembly (No Piston) – Pistol Suppressor Accessory

The Yankee Hill Machine Co Nielsen Booster Assembly is a critical component for running pistol suppressors on tilting-barrel semi-automatic handguns. This booster (also called a linear inertial decoupler or LID) allows the barrel to recoil and unlock properly when a suppressor is attached, ensuring reliable cycling. Without a booster, the added weight of a suppressor can prevent the slide from operating correctly. This assembly does not include a piston—purchase the appropriate threaded piston separately based on your host firearm's barrel thread pitch.

The YHM Nielsen Booster Assembly is precision-machined from durable materials and features a hard-anodized finish for corrosion resistance. Installation is straightforward: thread the appropriate piston (sold separately) into your barrel, then attach your suppressor to the booster assembly. Compatible with YHM pistol suppressors and many other brands that accept Nielsen-style boosters. Verify compatibility with your specific suppressor model before ordering.
