Product Overview
Dead Air Sierra 5 – Compact 5.56 Suppressor (KeyMo / Xeno)
The Dead Air Sierra 5 is a dedicated 5.56 suppressor built for professional and hard-use shooters who demand durability, control, and repeatable performance. With a fully welded Stellite baffle stack inside a stainless outer tube, the Sierra 5 balances sound and flash reduction with a compact footprint that pairs perfectly with modern 5.56 rifles and SBRs.
Purpose-Built 5.56 Suppression
Optimized specifically for 5.56 NATO, the Sierra 5 offers a strong blend of sound suppression, flash mitigation, and manageable back pressure. It excels on short gas guns, duty carbines, and training rifles where reliability and repeatable point of impact are critical.
