Ridgeback Defense Rhodie 6K Compact 6mm Suppressor

Ridgeback Defense Rhodie 6K Compact 6mm Suppressor

The Ridgeback Defense Co. RHODIE 6K was built on a simple but uncompromising premise: take everything that made the full-size Rhodie 6 one of the most respected suppressors in the duty and hard-use market — the advanced gas management, the deep controlled tone, the punishing reliability — and compress it into a form factor that disappears on an SBR and handles like it was never there. The result is 4.5 inches of Inconel-built, full-auto-rated suppressor performance that doesn't ask you to trade capability for compactness.

One inch shorter than the Rhodie 6 and purpose-engineered for the platforms that need it most — SBRs, duty rifles, and hard-use carbines — the RHODIE 6K maintains the same advanced gas management architecture that keeps back pressure very low and sound signature tightly controlled, even on short barrels where lesser cans struggle. Optimized for 5.56 and 6mm carbine platforms and rated for 10.3" barrels and up, the 6K doesn't flinch at high-velocity gas volumes. It manages them — delivering a measured 138.1 dB average on the SOLGW MK1, a minimal flash signature, and the deep, smooth tone that Ridgeback Defense suppressors have become known for.

Constructed from Inconel — the same aerospace and high-temperature alloy trusted in jet engines and military applications — the RHODIE 6K is full-auto rated for 6 magazines in one minute. When your carbine is running hot and the firing schedule shows no signs of slowing, the 6K is still doing its job without hesitation. Finished in Black, FDE, or Raw and compatible with direct thread or Plan B short-configuration mounting via the 1 3/8x24 HUB, the RHODIE 6K is ready to mount, ready to run, and ready for whatever comes next.

Advanced Gas Management System:
The RHODIE 6K carries forward the same internal gas management architecture as Ridgeback's full-size Rhodie 6 platform, delivering the very low back pressure, controlled sound signature, and deep smooth tone.

Inconel Construction:
An aerospace-grade nickel-chromium superalloy engineered to maintain structural integrity under extreme heat and pressure.

138.1 dB Sound Performance:
Measured at a 5-shot average of 138.1 dB on the SOLGW MK1, the RHODIE 6K delivers real, quantified suppression performance on a real-world duty carbine.

Ultra-Compact 4.5" Form Factor:
One inch shorter than the full-size Rhodie 6 and measuring just 4.5 inches in total length at 1.75 inches diameter, the RHODIE 6K is specifically proportioned for SBRs.

Very Low Back Pressure:
The RHODIE 6K's internal geometry is engineered to minimize gas blowback into the action — keeping the shooter's face clear of propellant gases during suppressed fire.

Minimal Flash Signature:
Effective flash reduction keeps the shooter's night-adapted vision intact and minimizes the shooter's visible signature during suppressed fire.

1.375x24 HUB Thread Compatibility:
Compatible with the widely adopted 1.375x24 HUB mounting standard, the RHODIE 6K supports direct thread attachment and any short-configuration Plan B mounting option.
