Dead Air DA409 P-Series Fixed Barrel Spacer 1.20 in

The Dead Air P-Series Fixed Barrel Spacer is a drop-in service part that installs inside a P-Series Booster Assembly so Dead Air P-Series handgun suppressors can be safely and correctly used on firearms with fixed barrels.

By replacing the booster spring inside the Nielsen device, the spacer locks out spring travel and prevents the piston from cycling. The suppressor then behaves like a direct-thread mount, holding the can securely locked up on hosts that do not generate the motion needed to operate a standard booster. This makes the DA409 ideal for any fixed-barrel host where a standard P-Series booster cannot cycle normally.

Designed by Dead Air, the spacer is fully compatible with Dead Air P-Series pistons and the SD500 P-Series Booster Assembly. Measuring just 1.20" long, it installs inside the booster housing without permanent modification, and can be removed to restore standard booster operation on tilting-barrel hosts.

Whether you are running a P-Series can on a fixed-barrel host or simply need a way to keep a P-Series suppressor locked up without standard booster cycling, the Dead Air P-Series Fixed Barrel Spacer keeps things running as intended.
