Description
Titanium suppressors usually ask you to trade toughness for weight savings. The Radical Defense LS-5Ti splits the difference nicely. It's 3D printed from Ti64 titanium as a single monolithic, implosion resistant structure, which means no stacked baffles to shoot loose and no weld seams to worry about when the can gets hot. It carries a full auto rating and is built to handle sustained fire while still knocking down sound, flash, and thermal signature on 5.56 platforms.
Why the LS-5Ti Runs So Clean
The standout feature here is Radical's forward venting Breathable Technology. Instead of dumping all that gas back into your receiver, the LS-5Ti stabilizes internal pressure and pushes it forward, which translates to noticeably less blowback in your face, smoother cycling, and less carbon fouling in your action. Anyone who has run a traditional sealed can on a short gassed AR knows exactly why that matters. Your bolt carrier stays cleaner, your eyes stay clearer, and the rifle just behaves better.
Built for Rough Environments
This one wears a proprietary I/R non-reflective coating in flat dark earth, so it stays subdued under night observation devices instead of glowing like a beacon. The titanium construction is also salt air resistant, making it a solid pick for coastal duty or anywhere corrosion eats lesser cans alive. At 7.5 inches long with a 1.75 inch diameter, it's sized for real suppression rather than bare minimum hearing protection.
Mounting the Radical Defense LS-5Ti
The rear of the can uses the industry standard 1.375×24 HUB pattern, so you're not locked into one mounting ecosystem. Out of the box it comes set up with Radical's KFM taper mount flash hider in 1/2×28, which requires zero modification to your host rifle. Thread the muzzle device on, spin the can down on the taper, and you're set. If you already run HUB mounts from other makers, this can plays along just fine.

Frequently Asked Questions
What mounting system does the Radical Defense LS-5Ti use?
The LS-5Ti uses the industry standard 1.375×24 HUB pattern at the rear of the can, and it ships with Radical's KFM taper mount flash hider in 1/2×28. That means no permanent modifications to your rifle, and if you already own HUB compatible mounts from other brands, you can run those too.
Is the LS-5Ti full auto rated?
Yes. The LS-5Ti is rated for sustained full automatic fire thanks to its monolithic, implosion resistant Ti64 titanium construction. It was designed to provide sound, flash, and thermal mitigation even under high volume shooting, so semi-auto range days won't come close to stressing it.
Does the LS-5Ti reduce gas blowback?
It does, and that's one of its biggest selling points. Radical's forward venting Breathable Technology stabilizes pressure inside the can and vents gas forward instead of back through your receiver. The result is less gas in your face, reduced back pressure on the action, smoother cycling, and less carbon buildup over time.
What is the difference between the LS-5 and the LS-5Ti?
Both share the same 3D printed, low blowback design, but the standard LS-5 is built from Haynes 282 superalloy while the LS-5Ti is made from Ti64 titanium. The titanium version trims weight off the end of your barrel, which makes a real difference in handling on a carbine, while still keeping the full auto rating and salt air resistance.
