Maximum volume. Maximum silence. No compromises.
The Bushmaster Carbon Silencer – Big Boy* is the absolute peak of sound suppression in the Bushmaster lineup. If your goal is to play as sneaky as humanly possible and make your HPA replica nearly disappear acoustically, this is the silencer you run.

This is the quietest model available. Period.

 

And only  about 253 grams

*previously called Compensator


Design Philosophy

The Big Boy exists for one reason: ultimate silence.
By increasing internal volume to the maximum practical size, this silencer delivers the highest level of sound reduction possible without adding noticeable weight or negatively affecting handling.

Despite its size, the Fat Boy remains surprisingly lightweight, meaning you won’t feel it much during gameplay — but everyone around you definitely will.

This model is trusted and used by top-tier stealth players, including Airsoft Camman, Kaslab, Rummbolt  Airsoft Dudes, and of course akicking Mustang who runs the Big Boy on his SRS / TAC41 sniper setups specifically because it is the quietest option available.


Available Size (Model Big Boy)

  • 180 mm / 18 cm
    Designed for players who want the absolute best sound reduction available.


Compatibility

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

  • Plug & Play — no modifications required

  • Compatible with all 14 mm CCW outer barrels (MTW, VSR 10 with adapter, AEGHPA conversions, Gate PTX pistol) 


Performance Notes (Important)

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

  • On HPA, this is as quiet as it gets —
    the difference is immediately and unmistakably noticeable.


Proof & Support

  • Instruction videos available on YouTube: callsign.bushmaster

  • Backed by extensive real-world testing and community feedback


Bottom line:
The Bushmaster Carbon Silencer – Big Boy is the end boss of silence. If stealth is your priority and you want the quietest possible HPA setup, this is the silencer you choose — no further upgrades needed.

Super Schalldämpfer der BigBoy. Habe den an einer MCX Rattler AEG montiert. Sieht hammermässig aus und der Klang ist geil.
Versand ging auch sehr schnell. Deshalb für alles 5 Sterne. Hätte auch 10 gegegeben, wenn das ginge.

I bought it because I wanted to see for myself if it really lived up to the claims made in the videos I'd watched, and I have to say it's by far the best silencer I've ever owned. We tested it on high-end Speedsoft replicas, and my friends were speechless. It truly is the quietest silencer on the market, and I recommend it 200%.

Excellent product and customer service. Fast shipping too. Works great with my HPA build. They included an extra foam pad and was helpful in answering my questions afterwards. Note: end cap is held on by tightening screws until cap is secured, but done over tighten.

The suppressor is a fantastic bit of kit! Super light, super silent, super deadly! But what's better is the customer service! I had a minor issue with the one shipped out to me, and almost immediately, my email was responded to, I jumped on a video call, and the issue was sorted out then and there, with 2 replacements being sent out to me asap! A great product, and a fantastic company to work with!

Das Gewinde war von Grundauf nicht tief genug, dies habe ich nachgeschnitten, nun passt alles und er passt komplett auf das Gewinde der SSX10

Nice job man 💪 this silencer is BY FAR the BEST!

tnx man. Its true that the first (few) times you need to use a bit of more force, thats by design. the first part is aluminium threading, and than 3D printed. your outer barrel will thread into it and create a perfect fit with your setup. But always contact me if it doesn't work or you have questions, happy to help. My whatsapp info is in the package. Enjoy your silent SSX10!
