Both the FLOW Range 36 and the FLOW 9k utilize a monolithic titanium core and tube, giving them strong durability, low weight, and high resistance to heat and erosion. Both models also feature Extended GeoFlash cap lugs which make the silencer easier to handle and remove when hot.

vs
FLOW 9K TI:
Which HUXWRX FLOW Suppressor Fits Your Needs?
Few design concepts have lowered the barrier of entry to suppressed shooting than HUXWRX Flow-Through technology. This comfort-first design solves longstanding issues of needing to fine-tuning gas systems and eliminates blowback to the operator’s face. HUXWRX offers many variations of their Flow-Through suppressors, but if you are looking for the most lightweight options available, your two top options are the highly versatile FLOW Range 36 Ti and the ultralight FLOW 9K Ti.
Both are fully 3D-printed from monolithic (single piece) titanium and offer considerable advantages. The Range 36 is a lightweight, multi-caliber rifle and pistol suppressor that ships with a HUB QD (quick-detach) adapter. The FLOW 9K is purpose-built as a lightweight pistol caliber carbine (PCC) option with a booster assembly included for handguns.
The question of Range 36 vs 9K comes down to your intended usage profile and your priorities for your build. Dive into our HUXWRX FLOW comparison and decide which option is best for you.

Build and Materials
Size, Weight, and Handling
FLOW Range 36: Carbines and Hunting Rigs
At 6.67 in bare (7.54 in with the included adapter), the Range 36 provides rifle-level suppression at under 13 ounces, adding minimal front-end weight on carbines, special purpose rifles (SPRs), and hunting rifles. For hunters or shooters wanting a single QD can that covers everything from 5.56 carbines to .338 Lapua rifles (with pistols up to 9mm thrown into the mix), the Range 36 is an excellent choice.
FLOW 9k: Pistols, PCCs, and SBRs
The FLOW 9K’s footprint is much slimmer and shorter: 5.33 inches bare or just under 6 inches with the booster assembly. At under 9 ounces even with the booster installed, it is one of the lightest Flow-Through suppressors available. For compact setups like 9mm PCCs, short barreled rifles (SBRs), or carbines up to 350 Legend, the reduced length maximizes handling while still greatly cutting down on muzzle blast.
Gas Control and Comfort
Both suppressors rely on HUXWRX Flow-Through geometry, which greatly improves shooter comfort by directing expanding gases forward instead of back toward the shooter. This dramatically reduces gas-to-face in AR platforms and blowback carbines.
On PCCs (where shooter comfort is often hampered by excess blowback) the FLOW 9K shines by keeping cycling smooth and the shooting experience cleaner without the need to fiddle with gas settings.
The Range 36 extends the same benefit across rifle calibers, preventing eye-stinging gas and keeping optics lenses cleaner.

Mounting and Ecosystem Fit
Both suppressors are QD-ready out of the box with the right muzzle device thanks to their included HUB adapters, ensuring cross-compatibility across the broader suppressor ecosystem.
The HUXWRX FLOW Range 36 Ti ships with a HUB QD adapter, making it compatible with the full HUB 1.375×24 family. Optional accessories include direct-thread adapters, 3-lug systems, and stiction-lock options.
The HUXWRX FLOW 9K Ti includes a 1/2×28 booster assembly and HUB piston adapter, ideal for pistols out of the box. Fixed-barrel spacers and 3-lug options can be added for PCCs and SBRs.
Caliber coverage and barrel rules
The Range 36 has some of the broadest multi-caliber coverage in the HUXWRX lineup, spanning from 22 LR to magnum cartridges like .338 Lapua and 8.6 BLK, easily accommodating common rounds like 5.56 and 7.72. With no barrel-length restrictions, it can be safely run on SBRs or long-barreled platforms alike.
The FLOW 9K is centered on smaller pistol calibers, yet doesn’t lack flexibility, handling everything from 22 LR to 9mm, including 5.7×28. It is also rated for both subsonic and supersonic 300 BLK, as well as large flat-walled cartridges like 350 Legend. Finally, it is full-auto rated for 300 BLK and has no barrel-length restrictions.
