Bushmaster Model Core Sound Mitigator: Ultra-light. Ultra-quiet. Built for stealth.
The Bushmaster Carbon Sound Mitigator – Core is the most popular model in the lineup for a reason: maximum sound reduction in a compact, lightweight package, optimized specifically for HPA platforms.

This is a field-tested (on snipers, MTW, HPA builds) sound Enhancer that dramatically reduces the report of your HPA replica.

Design Philosophy

Developed and refined through years of real-world use by myself, teammembers, youtubers like Kicking Mustang, Kaslab and Rummbolt and many many players all over Europe and the US. Every Core sound Mitigator is hand-assembled, extensively tested, and tuned for maximum efficiency per gram.

The Core hits the sweet spot between size, weight, and suppression. 

Compatibility

• 14 mm CCW (counter-clockwise) M4 outer barrels

• Plug & Play — no modifications required
  

Performance Notes (Important)

• Recommended for HPA replicas only
  AEG and GBB platforms gain minimal benefit from any sound Mitigator.

• The difference on HPA is immediately noticeable —
  you will be surprised how quiet your replica becomes.

Proof & Support

• Instruction videos available on YouTube: callsign.bushmaster

Bottom line:
The Bushmaster Carbon Sound Mitigator – Core is one of the quietest HPA Sound Mitigators you can run without going oversized. Lightweight, beautifully finished, and brutally effective.
