Suppressors

Suppressors — Military-Correct Configurations, NFA Guidance Included

A suppressor is the most transformative accessory you can add to a military clone build — and for clone builders, it's also a correctness issue. The KAC NT4 on a SOPMOD Block 2 M4A1, the KAC QDC on a Mk12 SPR, the Griffin M110 on an M110 SASS — these are not interchangeable. CCC stocks the correct suppressors for the correct platforms, and the team knows which suppressor belongs on which build.

The NFA Process — Simplified

Suppressors are National Firearms Act items requiring a Form 4 transfer and registration with the ATF. The process involves completing ATF Form 4, submitting fingerprints and a passport photo, and waiting for approval. As of January 1, 2026, the $200 NFA tax stamp fee has been eliminated — the paperwork process remains, but the cost barrier is gone. CCC will walk you through the process with every suppressor purchase.

What CCC Carries

Knights Armament NT4 — the SOPMOD Block 2 suppressor, correct for M4A1 configurations used by Army special operations. Knights Armament QDC — lighter, used on Mk12 and Mk11 configurations. Griffin Armament M110K1 — the SOCOM-contract suppressor for M110 SASS and Mk11 platforms. CCC sources these because they are the correct suppressors for the configurations we build — not because they are the easiest to stock.

Clone Correctness for Suppressors

The right suppressor for your clone depends on which unit, which year, and which configuration you're referencing. A 2003 Ranger Regiment M4A1 used the KAC NT4. A 2007 SEAL Team M4A1 may have used a different unit-sourced can. CCC knows these distinctions — since 2017, we have been the resource for builders who want to get the suppressor right.
